much soda are more fusible. Not acted upon by acids. 

Typical Sanidines exhibit numberless fractures with characteristic 
rents, which constantly alter their direction. They also frequently dis- 
play, upon their cleavages, a striation somewhat resembling a pseudo- 
twinning.

phyritically imbedded in epidotic " syenite " (Greg). Mainland, at 
Bixter Voe, similarly to the above (Dudgeon and H.). 

ORKNEY. Mainland, at the point of Ness, Stromness. From 
granitic veins in gneiss. Cream coloured Anal. 1. 

SUTHERLAND. Ben Hope, at Meallan Liath, with Hornblende, in horn- 
blendic gneiss. In a quarry north-west of Eibigill, with Albite, Sphene, 
and actinolitic Hornblende, mxc (Plate LIT., fig. 1); mxc (Plate LIL, 
fig. 2). At Jibigall, Melvich, in porphyritic crystals, with a zonal struc- 
ture, with Albite, in granitite. Lairg, at Cnoc Dubh, in veins in 
" syenite," of a pink colour, with Oligoclase, Sphene, Allanite, and 
Haughtonite Anal. 2. At The Ord, bright red, in veins in gneiss. 
Beinn Spionnaidh, on the north-west slopes, granular, pink, with Uralite 
and Sphene Anal. 7. Canisp, near the summit, on the east side, some- 
times with a sheath of Albite, in red porphyry in quartzite, mclzoy 
and mclog (Plate LIL, fig. 3); mclnzaoy, mc~boyn--z (Currie) ; 
ml} cog, hemihedral; twins of fig. 3 with interstitial Oligoclase twins 
(Plate LIL, fig. 6) and simple twins of fig. 3 (Plate LIL, fig. 6). 

EOSS-SHIRE. West of Struay Bridge, granular, and pink ; with blue 
Microcline, Beryl, Garnet, yellow Muscovite, and Tourmaline Anal. 4. 
In the red porphyry associated with the Torridonians and the Cambrian 
Quartzite of Canisp. Loose crystals of brick-red colour may be gathered 
in quantity from bare scalps on both sides of the summit of this hill. 
These are in simple crystals of the form mcbzoy and me bog. 



SILICATES. 3 

INVERNESS-SHIRE. Glenelg ; Gleann Beag, above Balvraid. Pale blue, 
with a waxy lustre (Necronite) in limestone, with Balvraidite, hydrous 
Labradorite, and dark grey-blue Malacolite -Anal. 5 (Dudgeon and H.). 

BANFFSHIRE. Near Tomintoul. Three miles above the junction of 
the Ailnack and the Avon, on the west bank of the former stream, with 
Entile and Chlorite, me (Plate LIL, fig. 7);mcbx (Plate LIT., fig. 8); 
m c n x. 

ABERDEENSHIRE. Bennachie, on the summit ridge, crystals with 
zonal Albite, in porphyritic granite. Eslie, in limestone (Nicol and H.). 

KINCARDINESHIRE. Banchory, at Cairnton. On the summit of Mount 
Shade, fawn coloured crystals, in red porphyry. At Clattering Bridge, 
colourless crystals, with zonal Albite, in porphyry dyke Anal. 6. 

HEBRIDES. Harris, on the south shore of West Loch Tarbert, of a 
deep red, in hornblendic gneiss. 

ARGYLLSHIRE. At Strontian, porphyritic crystals, purple-red, with a 
zonal coat of white, in granite, with Spherie and Haughtonite. Campbel- 
town, at Isle Davarr, in porphyry. 



SANIDINE, OR GLASSY FISSURED FELSPAR. 

HEBRIDES. Eigg, in the pitchstone of the Scuir, etc. (Greg). In the 
pitchstone of Oigh-sgeir, south-west of Canna. 

FIFESHIRE. Kinkell, in tufa, in hemitropes, with a singular internal 
structure Anal. 8. Elie, in dykes of basalt east of the Summer Tower 
[and in the agglomerate filling volcanic necks on the shore between Elie 
and St Monans]. Also in the tufa of the Kiucraig. Bin Hill, Burnt- 
island, in a dyke of basalt. West of Elie. [These remarkable occurrences 
of Orthoclase may be due to derivation from some felspar-bearing rock, 
similar in lithological character to the trachytes of the Garleton Hills, 
through which these trappean rocks have made their way. See also 
under " Hornblende," infra, and the Appendix.] 

LINLITHGOW. [?] Hillhouse quarry, in a dyke of columnar basalt. 

MIDLOTHIAN. [?] Blackford Hill, with black Augite, in large crystals. 

ARRAN. At Corriegills, in " pitchstone porphyry," along with plagio- 
clase (Allport). Glen lorsa, in the same kind of rock (Jameson) 
Anal. 8. Drumadoon, in opaque crystals in claystone porphyry 
(MacCulloch). 

PiOXBURGH. Peniel Heugh, Crailing parish ; at Ancrum House, " large 
crystals in porphyritic greenstone " (Nicol). Wooden Hill, Eckford, " large 
splendent crystals in a dark rock." Near Ancrum, at Bellsbutts, in 
large crystals, in a light green matrix. 



4 SILICATES. 

Erythrite, or Zeolitic Orthoclase, of flesh-red colour, underlies 
zeolites in cavities. It occurs pseudomorphous after Stilbite, Heulandite, 
and perhaps Prehnite. It is specially associated with Analcime, Prehnite, 
and Thomsonite, cmhny. It occurs at Bowling (Anal. 10) in Dum- 
bartonshire; at Boyleston, near Barrhead, at the Gryfe tunnel, near 
Greenock ; and at Berry Glen, in Ayrshire. [Some varieties of Erythrite 
have been placed by Dr Heddle with Albite.]

SILICATES. 5 

Pyr. B.B. fuses at 5 of Kobell's scale. Varieties containing much 
soda are more fusible. Not acted upon by acids. 

Microcline is in Scotland of much more frequent occurrence than is 
Orthoclase. It may be said to be the essential constituent of many 
granites and of most acidic gneisses and pegmatites. It exhibits the 
Microclinic structure in very varying development, and, generally, this is 
more apparent in the Microcline of those remarkable bands of granitoid 
rock [pegmatite] which traverse, in parallel courses, so many of the older 
metam orphic areas of Scotland. 

SHETLAND Mainland. Hillswickness, at North Quin Geo, brick- 
red, in veins, with Epidote, in gneiss. 

ORKNEY Mainland. At Inga Ness, Yeskenaby, in nodules in gneiss, 
near granite Anal. 1. 

SUTHERLAND. Near Tongue, in a vein in the " syenitic " boulder on 
Ben Bhreac; pale brown, passing to Amazonstone Anal. 2. Crystals 
of two types occur. Those found near the sides of the vein are simple 
and twin-crystals of the Carlsbad type. The crystals are sometimes 
much distorted, cmmfby (Plate LIIL, fig. 1); cmmfbyxoo' (Plate 
LIII., fig. 2); czz'lyxoo' (Plate LIIL, fig. 3); cmm'lzz'yoo f (Plate 
LIIL, figs. 4 and 5); c m m' b z z f y (Plate LIIL, fig. 6); cmmbzz' yxoo' 
(Plate LIIL, figs. 7 and 8); cmm'lzz'yx (Plate LIV., fig. 9); twins 
cmm'lzz'yxoo' (Plate LIV., figs. 10 and 11), with the axis of 
revolution vertical, c and x nearly coinciding, and showing the com- 
position by sutures which show the two halves of the twin mutually 
to interpenetrate. These crystals are associated with Eadiated Cleave- 
landite, Fluor, Orangite, Thorite, Magnetite, Babingtonite, Sphene, 
Ilmenite, and Zircon. Towards the centre of the vein crystals of the 
Manebach type occur. Two crystals of huge size were found, one 15 J 
inches along & and c, 10 inches over &, 8 inches over c; the other 12J 
inches along & and c, 8 inches over b, and 6 inches over c. The simple 
crystals are c I x (Plate LIV., fig. 12) ; c I m m'zz' xy (Plate LIV., fig. 13) ; 
clmm' zz' xyoo' (Plate LIV, fig. 14), and twins of the last (Plate LV., 
figs. 15 and 16); of clzz' mm' xyoo' (Plate LV., fig. 17); clmm'xyo 
(Plate LV, fig. 18), sometimes with the face o alternately hemihedral ; 
clzz'mmf oo' x (Plate LV., fig. 19), with the faces z and o alternately 
hemihedral; and c I z z' m in' o o' x y (Plate LV., fig. 20). These deeper- 
seated crystals are associated with Ilmenite, Specular Iron, radiated 
Strontianite, and Quartz. The plagioclase felspar, which forms the 
corded structure of the above Microcline, appears from the analysis to 
be Oligoclase. It is itself striated parallel to the cleavages of the Ama- 
zonstone crystal. The angle of the latter is 89'43.

SILICATES. 



GEAPHIC GRANITE. 

This consists in all cases of a nearly simultaneous intergrowth of 
Microcline, or, rather, of cross-hatched felspar, with Quartz, the corded 
structure of Albite or Oligoclase being generally absent. 

The Quartz crystals have their main axes parallel to the faces c 
and b of the felspar, as if imbedded in parallel growth in a simple 
crystal of the Baveno type. 

The Quartz, through dominance of crystallising power, preserves 
the angles of its faces ; but as there has been a deficiency of material 
for the formation of solid forms of Quartz, hollow crystals result. 

The structure is also deficient as regards several of the faces of 
the prism, but hollow summits of the crystals are successively formed, 
the one within the other, as the compound structure is built up. 

As the deficient faces of the Quartz crystals are on one or other 
side which faces "b of the felspar crystal, sections of the felspar parallel 
to c show an imbedded system of crystals of Quartz, which resemble 
fish-hooks of more or less regularly increasing size (and common 
polarity) linked one within the other, the hook being turned towards I. 

Again, sections parallel to a of the Microcline, which sections cut 
the Quartz crystals at right angles to their main axis, show more or 
less numerous angular sections thereof, according as the deficient prism 
or the hollow summit of the crystals happens to be cut across. 

In all cases in Scotland where graphic granite is found in situ, it 
occurs in granite [ = pegmatite] veins, the material of which has solidified 
from the sides towards the centre. Almost all such veins show this 
graphic structure when sectioned parallel to the sides of the vein, and 
the structure is most minute at the sides. 

It is only very rarely that the Quartz protrudes from the ter- 
minations of the crystals of felspar. 

The whole circumstances seem to point to the silica which has 
crystallised having been that portion which has been present in 
excess of the quantity necessary for the formation of the felspar. 

In such rocks as exhibit this structure on a micrographic scale, 
a radiation of the Quartz from many solidifying points has taken 
place. In some of the huge veins in which it is found in Scotland, the 
Quartz crystals hold a parallel position over large spaces; while in 
others in which the felspar has concreted in huge rude crystals, there 
is a radiation of the Quartz, generally from a single point in each 
crystal. The great vein in Chaipaval, Harris, and those in and 
opposite to the islet of Stromay, in the Sound of Harris, are examples

Albite is a somewhat rare felspar in Scotland, being, for the most 
part, confined to the red granite of Aberdeenshire the so-called Peter- 
head granite, wherein it occurs as a dominant constituent of the rock. 
In Shetland it occurs as one of the essential constituents also of the 
gneisses.

B.B. melts more easily than Orthoclase or Albite to a clear glass ; 
not affected by acids. 

In its habits in Scotland Oligoclase presents itself as the very 
frequent associate of the corded felspar in granitic veins only in one 
locality (Coyle) is it found in another association; the evidence as 
regards it is perfectly definite. It also constitutes the bulk of the grey 
granite of Aberdeen ; this I find to consist of a great deal of Oligoclase, 
little Orthoclase, little Quartz, very small quantities of Muscovite, 
and a good deal of Haughtonite, such a compound as G. Eose calls 
granitite. The hornblendic gneiss of the Cape Wrath district frequently 
consists almost solely of a granular mixture of Oligoclase and Horn- 
blende. No one who has become familiar with the ever-recurring exfil- 
tration veins called crocus by the quarrymen which lace the grey 
granite of Aberdeenshire, will hesitate in considering the well defined 
crystals of the white felspar of these veins to be as thoroughly good a 
species as the accompanying flesh-coloured Microcline. 

A similar association with Microcline is also to be seen in the veins 
whether intrusive or exfiltration which occur in hornblendic gneiss, as 
at Eispond and Geodha na Seamraig.

Silica, 25'6 Alumina, 77 Soda, 7 Lime ; and thus is nearly equivalent 
to a mixture of one part of Albite and one of Anorthite. In Scotland 
is typical of the limestones of the Highland Metamorphic Series, and of 
some of the eruptive rocks which are intimately associated with these 
limestones.

SUTHERLAND. In the Shiness limestone quarry, very rarely, in pale 
dove-blue or grey crystals in cavities of crystallised Sahlite, with Sphene 
and Pyrrhotite, pmtlxyso (Plate LVIL, fig. 1) ; p m 1 1 x s z o, twin (Plate 
LVIL, fig. 2); pmtlxzony, twin (Plate LVIL, fig. 3) (D. and H.). 
These crystals are striated, and when placed in weak acid the alternate 
plates are soluble therein. This indicates that the crystals are made 
up of reversed layers of Albite and Anorthite. 

INVERNESS-SHIRE. Glen Urquhart, in one of the Millton limestone 
quarries, very rarely, in large crystals, in the centre of crystals of Zoisite 
Anals. 1 and 2. This quarry had, in addition, only Quartz and pale

Bare associates are Native Copper and Pectolite (Grieve and H.) Anal. 3. 

840. Latrobite. 

Many authorities regard Latrobite as being a species distinct from 
Anorthite; others place them together. This is certainly ill-advised. 
Anorthite is a lime felspar, with only a trace of potash ; Latrobite is a 
potash-lime felspar. 

The classification of the felspars is essentially an alkaline one 
every consideration should make it so. Dana unites this with Anorthite 
from the quantity of its acid ; but it is doubtful if that quantity is the 
same as in Anorthite. 

Latrobite has different angles, and has much inferior hardness. 

The specimens I have were found at Dalnabo, in metamorphic lime- 
stone associated with Anorthite. There was very little of the mineral ; 

1 FeO, -11. 



SILICATES. 21 

from the appearance and hardness being the same as those of Rhodonite, 
it was taken for that species until the specific gravity was determined. 

The colour was pale rose-red, the structure fine granular, the lustre 
feeble, the hardness 5, the specific gravity 2'749. 

Two specimens from different parts of the quarry were analysed ; the 
first was pure, the second might not have been totally separated from 
Coccolite. 

Only one other locality of this mineral is known.

Many substances occur in Scotland, which, from their mode of occur- 
rence, their situation, their appearance, that is, a gradation in their 
outward change, and from a corroborative alteration in their constitution 
when analysed, give rise to the conclusion that they have been formed 
by what may be termed a gradually-increasing serpentinous change from 
other minerals, of which Enstatite, Augite, Hornblende, and Olivine may 
be taken as the types. Those who wish to consider the details of such 
transmutation may consult a chapter on the subject in the Trans. Roy. 
Soc. Edin., xxviii. (1878). It is here merely necessary that, through 
their immediate relationship to Augite, the following analyses be given :

HEBRIDES. Talisker Bay, Skye, in cavities in Tertiary basalt-lavas 
Anal. 1. Prince Charlie's Cave, Skye Anal. 2. Dearg Sgeir, Loch 
Scridain, Mull, in vapour cavities in basic lavas and dykes of Ter- 
tiary age. It occurs in two forms. One of these is in acicular divergent 
and rosette groups, such as Scolecite and Mesolite assume, and with 
rough and opaque crystalline terminations Anal. 3. The appearance of 
the other was precisely that which might be expected in a massive 
Gyrolite. Large folia, of pearly lustre, and of a distinct sea-green colour, 
passed from all sides to the centre. Generally these folia were flat ; but 
here and there they were twisted and interwoven. But the toughness of 
the specimen threw doubt upon the mineral being Gyrolite, and the 
analysis, No. 4, left no doubt that the mineral in question was simply 
an exceptional form of Pectolite (Heddle, Trans. Geol. Soc. Glasgow, 1892, 
pp. 241-255). See also Analyses 5 and 6. A mineral doubtfully 
referred to Pectolite occurs in the north-west cliff of Askival, Eum. 

ARGYLLSHIRE. Manor House, Oban, "in a rent in a trap dyke, 
lustrous, and cream-coloured " (Nicol) Anal. 7. Sp. gr., 2734.

in basic eruptive rocks, chiefly of Arenig age, in which it occurs in white, 
fibro-crystalline aggregations, some of which are nearly three feet in 
length, and are excessively tough Anal. 10. At Bougang quarry, 
Knockdolian, near Ballantrae, in white, closely-fibrous aggregations, as 
well as in small acicular crystals Anal. 11. 

EDINBUKGHSHIRE. Eatho, where Pectolite occurs filling what were 
originally large vapour cavities in a great sheet of Dolerite. It is of a 
pale greenish-grey in colour, with a silky lustre, and is excessively tough. 
Some of the cavities are not quite filled by the Pectolite ; hence the free 
ends of the aggregations sometimes assume a distinct crystalline form 
(Plate LX., fig. 1) which serves to show the isomorphism of the present 
species with Wollastonite. Analysis 12 was made from the ordinary 
fibrous variety, and Analysis 13 from the crystalline form. Pectolite 
occasionally occurs at Eatho also as an interesting pseudomorph after 
Analcirne. In the Dolerite quarries of Corstorphine it is not uncommon, 
and is compact and fibrous, and of a pale greenish-grey colour Anals. 14, 
15$. It occurs, rarely, also in the basalt of the Castle Eock of Edin- 
burgh, in nodular masses, with a diverging structure, translucent, and 
crystalline, of a pale yellowish colour, and associated with Prehnite 
Anals. 16, 17. It is said to have occurred, in a weathered state, at 
Lochend, on the east side of Edinburgh ; also at Salisbury Crags (Taylor). 

[The foregoing description has been compiled chiefly from Dr 
Heddle's published works, and partly from the specimens in the Scottish 
Mineral Collection.]

Non-aluminous varieties of Amphibole tend to pass into fibrous 
varieties. The fibres of Tremolite are sometimes very long, and so 
loosely attached as to be separable by the fingers. When such fibres 
are flexible they are termed 'Amianthus ; when rigid, but tough, Asbestus ; 
and when rigid, isolated, transparent, and brittle, Byssolite. When these 
fibres become matted and entangled they form a fissile or schistose stone 
of great toughness termed Nephrite, being one of the stones used for the 
manufacture of axe-heads. Similar arrangements of crystals of Actino- 
lite form actinolite schist, which sometimes occurs in quantity entitling it 
to be regarded as a rock-mass. 

[Most of the Scottish Actinolite is associated with rocks that have 
been deformed by earth-movements.]

Anal. 2 is an incomplete analysis of specimens from the Drift of the 
North of Ireland, in all probability ice-carried from Ailsa Craig. 

Originally observed by Professor Bonney in the granite of Socotra, 
but first described as a new species by Sauer. Occurs in granite [and 
rocks allied thereto]. 

AYRSHIRE. Ailsa Craig, in the grey ailsite or Ailsa hone, in 
minute ophitic patches, dark green, almost black, or of a rich brown. 
Also, very rarely, on the south-east side in crystals -f^th to th of an 
inch. Combinations: mbr tpz (Sollas); mlrtpa (Plate LX., fig. 1); 
mbrtpai (Plate LX., fig. 2); mlaic (Plate LXL, fig. 3); mbrtpi 
(Plate LXL, fig. 4); mbrt (Plate LXL, fig. 5); mbrtze (Plate LXL, 
fig. 6) ; mbrtzeo (Currie and H.). 

In the granophyric rock of Meall Dearg, in Skye, in an ophitic form 
(Teall). 

It has also been stated by Barren to occur in the trachytic rock of the 
Eildon Hills ; these latter occurrences, however, are only microscopic in 
the dimensions of the crystals. 

[96. Orocidolite (341). NaFe(Si0 3 ) 2 .FeSi0 3 . 

Usually occurs in a fibrous and asbestus-like form, in which the 
fibres are delicate, easily separable, but tough. Translucent ; lustre 
silky. Colour, indigo -blue ; streak, lavender. B.B. fuses easily to a 
black, magnetic glass. Comp., Silica, 50'3; Iron Protoxide, 35; Magnesia, 
2*2; Soda, 67; Water, 5*8. Regarded by some as a variety of Eie- 
beckite. 

The Scottish form is earthy and amorphous, and occurs coating the 
joint faces and other divisional planes of metamorphic and other rocks,

Tetragonal, [a, 100 ; p, 111 ; m, 110 ; ? 210 (on fig. 2) ; x, 311.] 

Generally massive. H., 4*5 to 5 ; G., 5 to 5 '4. Lustre brilliant- 
vitreous when fresh, but resinous when weathered. Fracture conchoidal 
when fresh, splintery when weathered. Colour, brownish-black to clove- 
brown. Comp., essentially 18 Silica, 73 Thoria, 9 Water. 

Orangite and Thorite are thrown together because there is no ques- 
tion of their being one and the same substance: that which is called 
Thorite being merely Orangite in a state of greater hydration. Differ- 
ences of colour may be seen to pass into one another with the greatest 
abruptness in the same crystal, and that so precipitately, that the 
passage may be termed immediate. There are several localities at which 
there are more or less grounds for suspecting the occurrence of this 
mineral, but it has been definitely determined only at two. The first 
is the great boulder at Tongue, where it is found in lumps up to the 



56 SILICATES. 

size of beans, both rich orange-yellow and black, rarely showing crystal- 
lisation. When definitely crystallised there, the form is that shown in 
Plate LXVIL, fig. 1. Its associated minerals here are so numerous 
that a list, arranged in the order of their occurrence from the outside 
of the vein which carries them inwards to its centre, may be given. 
These are Babingtonite, Fluor, Sphene, Allanite, the Thorite, Magnetite, 
Lepidomelane, radiated Cleavelandite, Ilmenite, Amazonstone, Oligoclase, 
Quartz, Specular Iron, Bhreckite. 

This occurrence, seeing that this is a huge erratic, though almost 
unquestionably from Beinn Laoghal, cannot be regarded as other than 
unsatisfactory. 

The second locality where it occurs is in rude veins which protrude 
from the face of the great cliff of Beinn Laoghal, Sgor a' Chonais-aite. 
Here it occurs in crystals showing four different forms. Two of these 
show only pyramidal faces, in which the angle of the pyramid seems to 
depart so little from that of the regular octahedron that it cannot be the 
primary p face which is here disclosed. The second form is the square 
prism terminated by the pyramid as shown in Plate LXVIL, fig. 1; next, 
and this crystal is the most common, is the form depicted in Plate LXVIL, 
fig. 2 ; and lastly, there are two distinct octahedra, about half the size of 
peas, which, as before mentioned, seem to be the regular octahedron. The 
following difficulties stand in the way of the definite determination here. 
There is, firstly, the objection to the destruction of the specimen, and, 
secondly, the fact that the surfaces of both crystals are much pitted, and 
so dull that they would afford no reflection. But the fracture, both of 
the pyramidal and of the octahedral crystals, is conchoidal, the lustre 
pitchy, and the colour deep brown. In addition to their being non-mag- 
netic, there is no risk of here mistaking Magnetite for whatever mineral 
these octahedra may be, as the Magnetite here is blue-black, with distinct 
cleavage, and hackly fracture. And, again, the internal structure of 
the crystals which occur in these two irreconcilable forms is no more 
like that of a pseudomorph in the one case than it is in the other. The 
octahedral crystals do not resemble Pyrochlore. The pyramidal mineral 
is soluble in hydrochloric acid, with separation of silica; and the 
orange-coloured solution gives a copious ruddy precipitate with ammonia, 
which, taken along with the form, is sufficient to determine the tetra- 
gonal mineral as Thorite. 

At its second locality the mineral is, next to Amazonstone and 
greasy-looking Quartz, the most frequently-occurring substance in the 
veins, but it is usually in particles too small to be broken with advantage 
for collecting it. The associated minerals at this second locality are 
Babingtonite, Topaz, Eubinglimmer, Galena in small specks, and Sphene.

itic rock, associated with Scolecite (Currie). 

ABERDEENSHIRE. Glen Gairn, in the limestone quarry of Dalnabo. 
camber v (Plate LXXI., fig. 1), pale green to colourless, with Idocrase, 
Coccolite, Anorthite (Anal. 1) ; also forming pseudomorphs after Anor- 
thite Anal. 2. In a quarry on [? Creag Mhor, 2 miles north-west] of 
Crathie, associated with Wollastonite and Coccolite. 

ARGYLLSHIRE. At the Manor House, Oban, as a crystalline, pale green 
lining of a trap dyke traversing schist. The Prehnite underlies Pectolite 
(Nicol). Glencoe, about two miles above the lake [Loch Triochatan], 
near the road side at the foot of Am Bodach, in near association with 
green Epidote, Byssolite, and Chlorite. In a quarry five or six miles 
west of Dunoon (Blackwood). 

KINCARDINESHIRE. At Tremuda Bay, near Stonehaven, calm (Plate 
LXXI., fig. 2). 

PERTHSHIRE. In Glen Farg (MacCulloch). At the south end of the 
cutting made in 1888 ; pale green per se ; and sometimes crystallised, 
with Chalcocite, Native Copper, earthy Malachite, and Calcite. Some- 
times pinkish in colour, and associated with Datolite (A. Craig 
Christie). 

FIFESHIRE. Rarely, in a dyke in Kinness Burn, 1 mile west of St 
Andrews, along with Apophyllite. In the cliffs west side of the Island 
of May, with Scolecite and Datolite (Fleming). 

STIRLINGSHIRE. At the Campsie Hills, in the vapour cavities of Lower 
Carboniferous lavas, in which it occurs in the form of radiated, globuli- 
form, mammillated groups of crystals, of a pale green colour, and often 
accompanied by Thomsonite, me, meal, alcsnv (Greg). At the 
north-west end of the Mugdock tunnel, in dark greyish-green mammil- 
lations, associated with plates of Native Copper. 

DUMBARTONSHIRE. Near Frisky Hall (Bowling quarry) (Jameson), 
in large quantity, chiefly in two great veins which traverse the quarry 
from west to east ; but also occasionally in isolated druses in the north 
part of this quarry ; comb, cmab (Plate LXXI., fig. 2). The Prehnite is 
nearly persistent throughout these veins, though occasionally, where the 
veins are not so strong, it gives place to one or other, or to several, of 
the other zeolites mentioned below. Its character at different parts of 
the veins changes materially. Where the vein-structure is most marked, 
the Prehnite is in sheets, flat, fibrous, and of palecolours, and has indis- 
tinct terminations Anal. 3. Where the veins break up into lines of 



SILICATES. 71 

more or less separate druses, the colours become finer, the mammillations 
more prominent, and the individual crystals more isolated, and so more 
perfectly formed. Occasionally the association of one or more of the 
other zeolites seems also to effect this more perfect assumption of 
definitely crystallised terminations. The associated minerals, which are 
generally in the smaller offset veins, are Analcime, Thomsonite, Natrolite, 
Laumontite, Harmotome, Barytes, Edingtonite, Chabazite, and Stilbite. 
The two last named are always in separate veins. The general combina- 
tions of the crystals in the veins are calms and cabmsnv (Plate 
LXXL, figs. 3 and 4). S. G., 2, 885 (Haidinger). 

Very frequently the pale green fibrous Prehnite passes at one end of 
the fibres into milk-white solid Pseudo-Analcime. The structure of this 
is a mass of matted fibres at the faces of the crystals, while their usually 
hollow centres show mammillations of a green or, rarely, of a bright 
yellow Prehnite. The colours of the vein-Prehnite are, at the west end 
of the veins, brownish-white ; at the central portions, of a vivid light 
green ; while at the east end, when the colour departs from the usual 
dull green, it is either bluish-white (with the surface of the mammilla- 
tions so smooth as to have a chalcedonic appearance), yellow-green, or 
sulphur-yellow. In the cavities the crystals are generally isolated, 
calm (Plate LXXL, fig. 2), and the associates, if there are any, are 
Natrolite and " Prasilite " (or crystalline Saponite). 

Dumbarton Eock, with capillary Mesolite, in basalt (MacCulloch) 
Anal. 5, 5a. In Cochno Burn (Jameson). Near Loch Humphrey (Jameson).

groupings, of a fine yellow or orange colour, associated with Barytes and 
Calcite (Jameson). In a vein immediately to the east of Samson's Eibs, 
Arthur's Seat, in flabelliform groups, of yellowish-green and greyish-white 
colours. In the Calton Hill tunnel, with Analcime (Eose). In the great

beck brown mica (? Biotite), Calcite, and Amethyst (Eose), casn, casr 
(Plate LXXIL, figs. 6 and 7). In the east quarry, pale green, and, some- 
times, pink, with Augite, Labradorite, Amethyst, and Harmotome. Some- 
times with Apophyllite (Bryson). Barn ton, in veins in Picrite (Goodchild).

fig. 8), of a rich brown colour (Stuart Thomson). In a quarry on the 
east side of the Edinburgh road to South Queensferry, near Dalmeny, 
cam^n (Plate LXXIL, fig. 9) (Craig Christie), unassociated. 

EENFREWSHIRE. At Hartfield Moss (Jameson), waxy-white, opaque, 
and radiated, associated with Cluthalite and Analcime, not infrequently 
assuming the form of the latter (Greg) Anal. 7 ; grey in colour, and, 
in appearance, like Chalcedony, associated with Saponite. Also crys- 
tallised, cm ah At Bishopton tunnel (Jameson). Some specimens, 
associated with sheafy Thomsonite, Galactite, and Calcite, are perfectly 
botryoidal, each grape- like group of crystals being only just in contact 
with those adjoining such as these are bright green in colour. Others, 
associated with Greenockite, are in spheres, imbedded in a wackenitic 
paste. Eare specimens, which are associated with Datolite, though of 
paler colour than these latter, are in exquisite groups of fasciculitic tufts 
and spheres. Harmotome, Analcime, and Galena are here rare associates. 
At Boyleston quarry, Barrhead, in large quantity, and solely in mis- 
shapen druses in the harder portion of a porphyritic basic lava. Free 
crystals are very rare. The associates are Native Copper, which is 
frequently disposed in filaments and needles between the brushes of 
Prehnite, and which colours them brown-red, Analcime, Natrolite, 
Thomsonite, Malachite, Kubinglimmer, and variously and finely- 
crystallised Calcite. The Prehnite is usually of a pale green colour, 
but isolated hemispheres occur, which are of a fine yellow colour, and 
are sometimes disposed over, or among, the crystals of Analcime. Earely, 
some druses contain lustrous groups of an exceedingly light green and 
milk-white colour. Mickle Cloak, Lochwinnoch, in dull, radiated, dead- 
white crystals (Montgomery).

Gyrolite was unquestionably observed and recognised as a new 
mineral species quite independently by MacCulloch, Haidinger, Giesecke, 
and Earl Compton ; but the mineralogical science of their days was not 
sufficiently advanced to enable them to individualise it as a species. 
MacCulloch (Trans. Geol. Soc., vol. iii.) writes of it : Mesotype one 
variety " is disposed in a radiated or rather in a ramose manner, in fine 
fibres possessing the peculiar lustre and softness of the finest white pulverulent 
Talc. ... In a third instance, which I observed near Loch Eynort, a 
mass of globules of solid radiated Mesotype, very much resembling some 
of the oolites, is intermixed throughout with farinaceous scales of the 
same substance, having the greasy aspect and lustre already described. In 
speaking of this substance, I have, according to common usage, ranked 
it with the Mesotypes ; it appearing to have been thus placed, partly 
because it is found associated with them, and partly because of the 
theoretical views which have been held respecting its origin. It will 
be for mineralogists of more authority to consider whether it does not 
deserve a separate place as a species, the question is evidently of a nature 
not to be determined by geometrical analysis, as far at least as the 
varieties already found extend; and the delicacy and uncertainty of 
unassisted chemical analysis in questions of this nature are far too great 
to tempt us to seek a new place for it by this kind of investigation." 

In the fifth volume of the Trans. Geol. Soc. London, again, we find

Earl Compton, in the year 1821, giving, among a list of minerals which 
occur a little way inland, and behind the farm-house of Carsaig, " Anal- 
cime, a foliated Zeolite" In volume vii. of the Edinburgh Journal of 
Science, it is stated, at page 19, that Giesecke discovered what must 
have been Gyrolite, terming it " micaceous Apophyllite or a sub-species of 
Apophyllite " ; and giving as its locality Nia Kornak, in Disco, where it 
occurs in vesicular cavities in basalt, associated with Apophyllite, and 
Mesotype in one specimen with Chabazite and Levyne, of the specific 
gravity of 2-382. In the same volume, of the date 1827, in a paper in 
which Haidinger considers the varieties of Mesole, he writes : " Though 
even now I cannot pretend to offer a perfect description, the more accurate 
indication of the regular forms being yet a desideration, yet the crystals 
which I have examined of these new varieties are such that the place 
of Mesole in the system of Mohs may be fixed with precision." After 
excellent descriptions of typical globular varieties of undoubted Mesole 
from the cave of Naalsoe, he thus describes this species : " VI. Reniform 
groups with a single cleavage: very bright, pale yellowish-grey, from 
Ma Kornak, Disco. This new variety shows a very great resemblance 
to certain kinds of Apophyllite, so much so, that Sir Charles Giesecke, 
who discovered them, was induced to consider this as a particular sub- 
species, terming it the micaceous Apophyllite." The seventh specimen 
is described as " occurring in plates, which have a bright pearly lustre, and 
thin cleavage planes ; the whole aggregate resembles, in no small degree, 
crystallised spermacetie form part of the inside of a geode at Karartut, 
near Godhavn, Disco colour somewhat yellowish; eighth specimen, 
large, aggregated, uniform shapes, colour yellowish-grey, cleavage easily 
obtained, and the laminae show some elasticity when you attempt to 
separate them," also from Nia Kornak, in the Umanakefjord, Disco. 
Haidinger remarks upon its perfect simple cleavage, its marked pearly 
lustre. u Its specific gravity being above 2*3, is much more considerable 
than that of either Stilbite or Heulandite, which hardly ever exceed 
the limit of 2-2, an immense difference in species whose specific gravity 
is at the same time so inconsiderable and so constant as in the genus 
Kouphone Spar. In this property it nearly agrees with Apophyllite, 
but is readily distinguished in its crest or fan- like aggregations, the 
like of which never occur in Apophyllite, yield also a good empirical mark, 
although the crystals hitherto observed are too small, or, rather, too thin, 
to allow of an exact determination. In allusion to these aggregrated 
groups and the kind of fracture depending upon it, I propose Flabelli- 
form Kouphone Spar as the systematic denomination of the species, the 
first varieties of which were described by Berzelius under the name 
of Mesole." [The author has slightly modified Haidinger's phraseology.]

Haidinger adds : "It is worth noticing that this species, when it is 
associated with Stilbite or Apophyllite, will always form the lowest 
stratum immediately adjoining the basaltic, or amygclaloidal, support 
in the cavities of which it is deposited." 

In this paper of Haidinger's we have a retrograde step, for though 
he clearly separates the mineral from Apophyllite, yet he does so at 
the cost of associating it with Mesole, a substance from which it differs, 
both physically and chemically, to a still greater extent than from 
Apophyllite.

Twins very rare. Twin plane p. Habit of the crystals varied from 
extreme differences in the lengthy of the upright axes, and also from 
the relative size of the face p, which produces a more or less perfect 
acute pyramid. Appearance of the faces characteristic. The terminal 
face c often rough ; p more generally uneven ; y striated parallel to its 
intersection with a. Civ., c perfect. Fracture uneven. Brittle. H., 
4-5 to 5'5 ; G., 2*3 to 24. Lustre of c pearly ; of the other faces vitreous. 
Colourless, to white, pale emerald-green, or rose-red. Streak white. 
Transparent to opaque. Double refraction weak; generally positive. 
Unbroken crystals in polarised light exhibit a beautiful tesselated struc- 
ture, of which the tesselee have curvilinear outlines, and differ much in 
form. No water lost by heating to 100, nor by exposure over sulphuric 
acid. All the water that is driven off at temperatures under 300 F. 
is reabsorbed; but only after very prolonged exposure to moist air. 
Werner found that Apophyllite was soluble in water at 180 to 
190 C. under a pressure of from ten to twelve atmospheres. Bunsen 
found that at all the ordinary temperatures not a trace is soluble 
under pressures ranging from twelve to seventy-nine atmospheres. In 
the closed tube exfoliates, whitens, and yields an abundance of water, 
which affords an acid reaction. In the open tube, when fused with 
salt of phosphorus, often gives a fluorine reaction. B.B. it exfoliates, 
colours the name violet through the presence of potash, and fuses with 
intumescence to a white blebby enamel ; with salt of phosphorus yields 
a skeleton of silica. Fusibility = 1-5 of Kobell's Scale. In powder it 
is easily soluble in acid, leaving a slimy silicious residue ; but if it has 
been previously exposed to a red heat then it is decomposed only with 
difficulty.

The lithological range of the rocks yielding this mineral is very 
limited. We find it occurring in the intrusive dolerites as well as in 
the contemporaneous basalt lavas associated with the Lower Carboni- 
ferous Eocks of the Basins of the Forth and Clyde. It is also associated 
with the basalt lavas of Tertiary age, occurring in the Western Islands 
of Scotland. It is found, rarely, in both large and small crystals, 
associated with Elaterite, in one of the limestones interbedded with the 
Lower Carboniferous basalt lavas. It likewise, formerly, was found at 
Strontian, in the vein which lies between the granite and the gneiss 
this mode of occurrence being similar to some on the Continent. 

Apophyllite would appear to be the very last zeolite to separate and 
solidify in drusy cavities ; and it does not seem to affect many associates. 
At Eudha nan Clach, in Skye, where there are some druses which 
contain four zeolites along with Calcite, it holds itself apart, and 
appears only in cavities per se. It seems also to be peculiar as regards 
these associates confining itself almost entirely to the company of Gyro- 
lite, Pectolite, and Prehnite minerals which may be said to fringe the 
borders of the class of the true zeolites.

Fig. 11 may be taken as the typical form for Scottish Heulandites. 
Undue elongation along each one of the three axes may be seen in the 
figures above referred to. Figs. 7, 8, and 9 present very unusual de- 
velopments ; and it may be remarked that an apparently re-entering angle 
on the faces t and s of the Heulandites from Ben More raises some doubt 
as to the primary form. 

In amygdaloidal eruptive rocks which contain free zeolites and at the 
same time much Calcite, minute crystals of red Heulandite generally line 
the druses. Such crystals also occasionally form the inner part of the 
lining of Celedonite which coats the vapour-cavities in which Agates of 
both the ordinary type and Moss Agates occur.

Faces b and m striated parallel to their mutual intersection. Appa- 
rently always twinned: generally these twins are duplicated by inter- 
section, and are frequently arranged so that three of the double twins 
just mentioned intersect at right angles to each other, and thus give rise 
to doubly-cruciform aggregates. When the prismatic faces of these latter 
are short, the m faces of the intersecting individuals form nearly one plane.

crystals, associated with Analcime and Mesolite, r,rsa, r esa, all 
twins (Plate LXXXL, fig. 5). At the foot of the crag of Leacan 
Fhionn, and on the hill north of Sgurr Mor, Quiraing, r, esta, both twins, 
and associated with many other zeolites. On the north slopes of Beinn 
Edra, associated with Analcime, etc., r z (Plate LXXXIL, fig. 6). At Lyn- 
dale in simple crystals r, ra, ret, (Plate LXXXIL, fig. 7), resa, re a, 
and rsz, (Plate LXXXIL, fig. 8); also twins of rs, re a, resa, rest, 
rest a, and res (Plate LXXXIL, fig. 9). Crystals like those given by 
Greg and Lettsom (Brit. Min., figs. 2 and 7) also occur, as do twins of t a, 
with small crystals of intrusion, resa, on the t faces, the a of the intrud- 
ing crystals falling into the same plane as the corresponding face of the 
large crystal. The striae of the smaller crystals occur so as to form a St 
Andrew's cross with the striae of the larger crystal (Plate LXXXIL, 
fig. 10). There has also been found at this locality a twin crystal com- 
posed of res and r combined (Plate LXXXIL, fig. 11); and also a hemi- 
trope of r s formed by a revolution of one-half of the crystal through an 
arc of 120 (Plate LXXXIL, fig. 12) ; and a similar twin of rzs (Plate 
LXXXIL, fig. 13). These for the most part occur without associates, 
and are much the finest crystals of this species found in Scotland. At 
Talisker (Anal. 1), chiefly near the sea stack at the south side of the 
bay, where this mineral is of a bluish colour, and of the forms rs, res, 
and twins of res. The Chabazite is associated with Analcime and 
with silky crystals of Mesolite. It also occurs in pinkish or flesh- 
coloured crystals (Acadialite), combinations r, r e, r t e, and twins of r, 
resa, rtes (Anal. 2) ; and in colourless crystals, r, r s, re, re s, 
unassociated with any other minerals. Crystals of each of the several 
colours occur apart from each other, and generally in separate vapour 
cavities ; and in the cases where the Acadialite is associated in the same 
cavity with the ordinary colourless Chabazite, the Acadialite occurs 
in twins of a more complex character than usual, while the normal 
Chabazite appears in the form of simple crystals. Chabazite occurs also 
on the north side of Talisker Bay in the form of simple white crystals, 
which are associated with Analcime Anal. 3. Loch Bracadale, at Eudha 
nan Clach Acadialite occurs with Analcime, and, more rarely, with 
Stilbite, Mesolite, and Apophyllite, these three latter occurring in associa- 
tion with the Acadialite in cavities separate from those which contain 
the Analcime. The faces of the crystals at this locality are curved. 
Sgurr nam Fiadh, on the coast between Talisker and Loch Eynort, in the 
form of milk-white, simple, crystals, measuring one inch across the face, 
which are the largest of the colourless form yet found in Scotland. These 
occur without any associates. At the same locality there is also found

pale Acadialite in occasional association with Gyrolite, Analcime, Pilolite, 
Laumontite, yellow Calcite, Scolecite, and Stilbite, and in the form of 
crystals with curved faces. At Orbost, on the north shore of Loch 
Varkasaig, Acadialite occurs over Faroelite, and underlying normal 
Chabazite. At the foot of the cliff of Beinn nan Cuithean, just to the 
south of Talisker Point. At the mouth of Allt Preshal Beg, 2 miles 
south of Talisker, associated with Analcime. At Geodha Tuill, Loch 
Eynort, associated with Scolecite. Eigg (Greg). 

ARGYLLSHIKE. In Mull (Jameson). Treshnish Islands, at the summit 
of Bac Mor, associated with Analcime ; rarely. At the south-east angle 
of Fladda, in twins of r, occurring over Scolecite. At the south end of 
Sgeir a' Chaisteil. over Scolecite. 

PERTHSHIRE. At Glen Farg (Greg). 

STIRLINGSHIRE. At Earls Burn Eeservoir, Touchadam Muir, in the 
form r, associated with Stilbite, Cluthalite, and Laumontite, on trihedral 
Quartz (Kidston). 

DUMBARTONSHIRE. In Bowling quarry, similar to " Glottalite," in 
twins of r s a (Plate LXXXIIL, fig. 14), coating the sides of fissures in the 
rock. Its sole associates here are Analcime, rarely, and Calcite. In Glen 
Arbuck, twins oietsar, like " Phacolite " (Plate LXXXIIL, fig. 15), occur 
in association with twin crystals of Calcite and with Saponite. 

RENFREWSHIRE, Port-Glasgow, " Glottalite " (which Greg ascertained 
to be merely Chabazite, ill-defined, nearly the form of Plate LXXXIIL, 
fig. 15) (Clacher). At Kilmalcolm (Thomson) (Anal. 4), of a brown tinge, 
and combinations r, r s, rs e, and associated with Stilbite, Heulandite, 
Sphreromesolite, and Calcite Anals. 4, 5, 6. At the same locality there 
is also found very fine Acadialite, in the form r, associated with zeolitic 
Quartz, Gothite, and, rarely, with normal Chabazite. It has recently 
been found in crystals an inch and a half across, of a brown tint, and of 
the combination r t s, associated with Stilbite, Calcite, and Mesolite. Said 
by Greg to occur at " Grainger's quarry, half a mile north of Alton 
House, two miles and a half south-west of Kilmalcolm." These are the 
largest crystals of this mineral found in Scotland. Boyleston quarry, 
Barrhead, in the south-west angle of the quarry, in the form of twin 
crystals of r, associated with Thomsonite.

minerals associated with Levynite, and that was a case in Skye, where it 
had minute crystals of Analcime superimposed upon it. (Plate

Water about 1 mile above Baidland limestone quarry, north-west of 
Dairy. 

"Boylestone quarry, near Barrhead in Eenfrewshire, is (or rather 
was, for it is temporarily at least exhausted) a storehouse of zeolites. It 
did not yield so many species as did the great quarry at Bowling ; but 
such specimens as Boylestone yielded were obtained continuously or 
regularly those at Bowling being got for the most part only when the 
two great Prehnite veins were being removed. In Boylestone, as in 
Bowling, Prehnite was very much the most common mineral; in the 
former Analcime stood next in frequency of occurrence, and was much 
more frequent there than it was at Bowling. 

"The appearance, though not the association, of the mineral is 
different in the two quarries. The groups formerly obtained at Bowling 
were cream-coloured, opaque, and dull on the surface ; the usual associate 
was Thomsonite, in groups of long radiating crystals. The crystals from 
Boylestone are white purer than what Ruskin calls ' paper-white.' The 
usual associate is still Thomsonite here, however, it is in bladed crystals, 
of the form which I have already described and delineated. 1 The speci- 
mens formerly obtainable of this Boylestone white Analcime were the most 
showy to be got from any British locality, being superior to the Irish 
specimens, and even to the pale blue variety from Talisker in Skye. 

" In addition to these opaque white specimens, however, Boylestone 
supplied us, though very much more rarely, with Analcime of an entirely 
different appearance. Upon the surface of mammillations of pale green 
Prehnite there were occasionally sprinkled isolated crystals of perfectly 
colourless and perfectly pellucid Analcime. It is certain of these only 
which carry the new faces. 

"The crystals of the specimen on which I first observed them are 
only about the sixteenth of an inch in size, and they do not, like the 
large and opaque crystals, in any way evidence a composite or tesselated 
structure. 

"The predominant form is the deltohedron n (211), but the crystals 
carry in addition the faces of the cube a (100) always irregularly 
developed; an adjacent very flat deltohedron w (m 11); the faces of the 
trigonal trisoctohedron r (332) truncating those edges of the leucitoid 
faces which converge upon its octohedral angles ; and an exceedingly 
narrow face lying between r and n. This last form is a hexoctohedron, a 
type which has not hitherto been observed in Analcime. The other 
edges of n seem also in some of the crystals to be bevelled. The two 
hexoctohedra are represented by such exceedingly narrow, although

102 SILICATES. 

brilliant, faces, that it has been impossible to measure them accurately 
with any goniometer at present in my possession ; they seem, however, 
to be z (543), and t (421) respectively. 

" The surfaces of the faces n are profusely pitted by a system of some- 
what symmetrically-arranged depressions of triangular form. These are 
exceedingly minute ; but reflected light and high magnification show that 
they are definitely bounded by the faces r and z t which form the sides of 
a very obtuse triangle, and by the faces a w, which form its base. 

"A highly magnified plan of their arrangement is shown [(Plate 
LXXXIV., fig. 8)]. 

" It has been stated above that the faces a are always irregularly 
developed ; they are generally, through the dominance of two opposite 
faces, reduced to mere lines. Inasmuch as everything points to the 
crystal of Analcime being composite one of the tesselites I had hopes 
that the direction of these lines whether they lay alternately at right 
angles to each other or not, or in any definite arrangement might indi- 
cate the system to which the primary crystal belonged. 

" In most of the crystals opposite sets of the leucitoid 3x8 faces 
truncate most deeply. This would seem to indicate a tetrahedral ten- 
dency, and crystallographic simplicity; and, as already stated, they do 
not exhibit the usual evidences of composite structure. 

" As is well known, the deltohedron n is the characteristic form of 
Analcime, and generally occurs alone. The only other form which is at 
all frequent is the cube. Out of over fifty different localities for this 
mineral in Scotland there are only [eleven] in which any form but n 
occurs, and in all these (except Boylestone) the sole additional form is 
the cube. These localities are Sands Geo in Walls ; Gapol (Kinneff) ; 
Glen Farg ; Kelly Law, near Elie ; Bowling ; Kilpatrick ; Hartfield, in 
Renfrewshire (Prehnite pseudomorphous after Analcime), Earlsburn, 
Ratho [Kinghorn] ; and, lastly, Boylestone. 

" The other forms which occur in Analcime are excessively rare, some 
of them being limited to a single locality. The only localities given by 
Hintze are 

"Friedensdorf, in Nassau, (211) (110) (100) (210) (332). Vesuvius, 
(211) (100) (110). Cyclopean Islands, (211) (100) (m 11). Phillip Island, 
Victoria, (211) (111). Kerguelen Island, (211) (332). 

" It is evident that the Boylestone specimens, which show the com- 
binations (211) (100) (332) (543) (m 11)... (421), narzw...t, are the most 
complicated yet observed of this usually excessively-simple mineral ; and 
it is certainly remarkable that while nowhere else in Scotland are crystals 
found showing more than two forms, those at Boylestone exhibit no 
less than six, of which two have so far never been found elsewhere. 



SILICATES. 103 

" It is worth noticing also, that although Analcime is one of the 
commonest zeolites of the Tertiary Traps of the Hebrides, the form there 
is invariably the simple deltohedron. All the Scottish examples men- 
tioned above, where the cubic faces are developed, are from igneous rocks 
of palaeozoic age. 

" A similar tendency to great (apparent) simplicity is observable in 
the crystals produced artificially, which are always either deltohedrons, 
or combinations of that form with the cube," HEDDLE, Trans. Edin.

Thomson mentions the Shiant Islands, Ayrshire, and also Dun 
Fionn, Arran, as localities for Natrolite. In all these occurrences the 
substance is more probably Mesolite. 

Crocalite is a bright red Natrolite, with a little lime replacing soda. 
It occurs in delicate tufted crystals, forming the caves of Quartz stalac- 
tites, at Long Gallery ; Tremuda Bay ; underlying Calcite, in large 
cavities, at Crawton Bay ; the Pulpit Eock ; and other spots along the 
coast of Kincardine shire ; in lustrous, divergent, brush-like crystals,

Montrose ; lining Calcite veins in a rotting dolerite, south of Wemyss, 
Ayrshire ; at Ballygroggan, Machrihanish Bay, Mull of Kintyre, in 
Barytes, and associated with red Heulandite. 

In the absence of Heulandite, flesh-coloured Natrolite is a common 
lining of calcitic druses in those amygdaloids which contain few zeolites. 
It is also frequently superimposed on Celedonite as a tufted lining of 
agate-druses, as at Scurr Hill, Ballindean, and Usan, near Montrose.

Monoclinic. Generally in the form of divergent groups of slender, 
prismatic, or acicular crystals. Twins on a common ; a feather-like stria- 
tion on face I ; the m faces often delicately striated horizontally. Cleav- 
age, ra perfect. H., 5 to 5*5 ; G., 2-2 to 2-3. Pellucid ; lustre vitreous ; 
colour white to reddish- white. Pyroelectric. B.B. twists into vermicular 
forms, melting readily to a porous glass. Only partially soluble in oxalic- 
acid. Comp., Silica, 45*8 ; Alumina, 26*2 ; Lime, 14-3 ; Water, 137. 

Natrolite and Scolecite pass into one another. There are two definite 
intermediate sub-species : Fargite (already noticed under Natrolite), 
which consists of two equivalents of Natrolite and one of Scolecite, and 
Mesolite, which consists of one equivalent of Natrolite and two of Scole- 
cite. Mesolite (to be noticed below) is the ordinary radiated zeolite of 
the amygdules in the basaltic eruptive rocks of the Hebrides and Faroes. 
In these rocks Mesolite occurs in matted groups of crystals of extreme 
tenuity [the " Cottonstone " Natrolite heretofore referred to]. In Een- 
frewshire Mesolite occurs in spheres with an internally radiated struc- 
ture, and also in acicular forms, and in downy tufts.

INVERNESS-SHIRE. Skye, Talisker, on the south side of the bay, past 
the stack, in small druses, in the form of brilliant, colourless, acicular 
crystals, which are very brittle (Eussell). Sgurr nam Fiadh, between 
Talisker and Loch Eynort. At this locality two vapour cavities contain- 
ing this mineral were found. One cavity measured 3 feet by 4 ; 
the other was 4 feet 6 inches high, 3 feet 6 inches wide, and 4 



SILICATES. 107 

feet deep. Both cavities were lined throughout with glancing acicular 
crystals of Scolecite, which were about one inch in length, and very 
slender and brittle. They were disposed upon pale green Celedonite. 
It also occurs, rarely, along with Mesolite, Faroelite, and Gyrolite, 
between Loch Eynort and Loch Brittle (MacCulloch). At the cliff-foot 
of Beinn nan Cuithean, on Chabazite. Geodha Thuill, Sgurr an Duine, 
and the mouth of Allt Mor, are also localities for this species. At the 
last-named locality Scolecite occurs in large brushes. At Kudh na h-Airde 
Glaise, near Portree, it occurs in druses, which are either totally filled 
with spherical groups of radiating bundles of crystals, which show no 
crystalline termination, or else, occasionally, have the central part of the 
cavity filled with Apophyllite over Gyrolite Anal. 1. On the west side 
of the Old Man of Storr, it also occurs in a similar manner Anal. 2. 
Such specimens (which contain soda) were termed " basement mineral " 
by the late Mr Thomas Brown of Lanfine ; and Dr MacCulloch argues, 
apparently from observations upon such specimens, which occur all along 
the coast of Skye from Loch Bracadale to Loch Brittle, that there is a 
passage from Mesolite through Prehnite into Chalcedony. Though this 
substance is a basement, that is to say, it is nearer to the rock than the two 
minerals that are here associated with it, other specimens show that 
Faroelite, Chabazite, and Heulandite all three occur in inferior position, 
and are therefore prior in date of deposition to the Scolecite ; the Faroe- 
lite being the earliest formed, or earliest solidified, of the zeolites in this 
case.

In prismatic crystals near Scolecite in form and angles, and twinned 
like those of that species. Lateral planes often vertically striated. Occurs 
in more or less divergent groups or tufts, often very delicate. Also 
found massive ; and in nodular masses of silky, fibrous crystals, which 
are disposed in a sphseroradiate structure. Sometimes consisting of 
interlaced fibres. Occasionally crypto-crystalline, or porcelain-like, or

INVERNESS-SHIRE. Skye, at Talisker, at the east foot of the Stack, 
in Tertiary amygdaloidal basalt lava ; on fasciculate groups of small 
pearly crystals which, although they delineate the form of spheres, do 
not assume the solid form as Faroelite does. These groups of crystals 
are associated in the same cavity with Acadialite, Chabazite, Mesolite, 
and Analcime. At Storr Thomsonite occurs, rarely, and in a manner 
similar to that at Talisker. A massive, granular, or confusedly-crystal- 
line variety of a chalk-white colour, which fills the druses, is also found 
at the Storr. It has a specific gravity of 2-139 Anal. 1. In some 
cavities this form of Thomsonite is associated with Saponite, which it 
overlies. At the foot of the cliff of Leacan Ehionn the crystalline 
variety occurs in association with Analcime, while the cavities adjacent

[In addition to the specimens found by Mr Thorns there are in the 
Scottish Mineral Collection in the Edinburgh Museum others found at 
" Monaltree Cliff," i.e. the Pass of Ballater, by the late Mr Thomas Bell of 
Ballygroggan. These occur in druses within coarse graphic granite, and 
are associated with Muscovite, red Microcline, Albite, and Smoky Quartz. 
The crystals show well-defined pseudo-hexagonal boundaries, are partly 
enveloped in the Quartz, and are succeeded by sheaves of small colourless 
crystals of Albite. Other similar specimens are from Culblean, Ballater.]

The brown mica in the matrix rock of Glen Gairn, Muir, Midstrath, 
etc., being very insoluble in HC1, may be Lepidomelane. 

[It may be useful to append here several analyses of dark micas, as 
they will serve to show the relationship of Biotite and Haughtonite to 
each other, and of Lepidomelane to both. The analyses are by Dr 
Heddle. Trans. Roy. Soc. Edin., xxix. p. 34.]

[The Prochlorite mentioned above from Glen Finnart is referred by

analysed. The Prochlorite from Beinn Dearg, and that from Girdleness 
(Analyses 2 and 8, above), and the Clinochlore from Dunoon and Bute 
(Analyses 5 and 6, above), which are all highly ferriferous, approximate 
in composition to Aphrosiderite, and may be referable to that not-very- 
well-defined species ; but it would seem more expedient to exclude from 
the designation those chlorites in which a considerable proportion of the 
ferrous oxide is replaced by magnesia (Currie).]

Varieties : Many species have been made out of Serpentine, differing 
in structure (massive, slaty, foliated, fibrous) or, as supposed, in chemical 
composition, and these now in part stand as varieties ; all would seem to 
be produced by an alteration of other substances. 

1. Chrysotile. Delicately fibrous, the fibres usually flexible, running 
transverse to the veins, and easily separating; lustre silky; colour 
white, golden-yellow, olive-green, brown. G. = 2'219. Often constitutes 
seams in Serpentine. It includes most of the silky Amianthus of Serpen- 
tine rocks and much of what is popularly called Asbestus. 

2. Picrolite. Columnar, but fibres or columns not easily flexible, and 
often not easily separable, or affording only a long splintery fracture ; 
colour dark green to mountain green, greenish, grey, and brown. 

3. Marmolite. Thin foliated ; the laminae brittle but easily separable, 
yet graduating into a variety, in which they are not separable. G. = 2-41 ; 
lustre pearly; colours greenish white, bluish white to pale asparagus 
green. 

4. Precious Serpentine. Generally short and brittle in structure ; oily 
lustre, rich green and red colours, with opaline reflections, translucent, 
but sometimes in ramifying veins passing to white and opaque. 

5. Bastite, or Schiller Spar, is Enstatite (Hypersthene), altered more 
or less completely to Serpentine. 

6. Williamsite. A lamellar Serpentine of apple-green colour, with 
H. = 4-5. 

7. Common Serpentine. Coarse and earthy, of blotched and variegated 
appearance, more resembling a rock mass. 

8. Pseitdomorphous Serpentine. Shows crystalline faces or outlines.

imbedded in black Serpentine. These on the rock surface are bronzy ; 
Chonicrite is an associate Anal. 11. 

Var. 7. Common Serpentine. 

This often forms great beds, or even mountain masses. It is a mix- 
ture of all the foregoing varieties, together with, probably, some Dewey- 
lite, Hydrophite, Pyrosclerite, or Kaolinite. It is also frequently veined 
with Dolomite or Calcite, and is studded with partially or completely 
pseudomorphosed crystals of Olivine, Enstatite, Sahlite, Actinolite, 
Nephrite, Chromite, or Picotite, and even felspars. These (varied con- 
stituents) often mottle it with red, green, or white, thereby giving it the 
aspect of a porphyry. The names Serpentine, Ophite, and Lapis Colu- 
brinus, refer to the serpent-like markings displayed when it is cut and 
polished; it is then, sometimes, improperly called Serpentine marble. 
This common Serpentine occurs in Unst (Anal. 15) and Fetlar, as the 
matrix of Chromite. Usually of yellow colour. 

SHETLAND. Unst and Fetlar. Several beds of Serpentine diverge 
like the blades of a fan from a point lying to the south of the last of 
these islands, and pass northward. The most westerly traverses both 
islands ; the two next in order traverse Fetlar, touch the islets Urie 
Lingey and Daaey, but do not reach Unst. The most easterly forms a 
large mass in Fetlar, the whole of Haaf Gruney (Anal. 12), and the 
promontory of Mu Ness in Unst. These beds are associated with lime- 
stones, gabbros, and gneissic schists. 

Mainland. A bed which appears first north of Ollaberry, crosses the 
heads of Quey Firth and Colla Firth voes, and reappears in Fethaland at 
Pundy and Klebber Geos. Other localities are the south-west extremity of 
Bixter Voe, Hillswick Ness and the south-west of Scousburgh, on the shore. 

INVERNESS-SHIRE. In Glen Urquhart, above Polmaily, in association 
with limestones and margarodite (Muscovite) schists. 

HEBRIDES. Lewis, at Loch Thamanabhaidh (Nicol). 

Harris, Scalpa Island, at Eilean Glas. Nearly crossing Harris from 
Scara Eudha to the Dun of Borve, north of Loch Langavat. 

BANFFSHIRE, ABERDEENSHIRE, and PERTHSHIRE. At Portsoy; two 
beds show themselves to the west of the town ; a series of thin beds in 
and on the west shore of Durn Bay, and two more massive ones near 
Cowhythe Head. These traverse in a S.S.W. course the counties of 
Banff, Aberdeen, and part of Perth, as two beds, sending an offset 
which forms a third about the Hill of Noth to the east ; this appears at 
several points, and passes into the sea north of Aberdeen. All seem 
united as far south as about Huntly, appearing on the east side of a 
quartz range, as at Damhead, near Durn Hill, Fordyce, Lurg, and Knock

several points at which the more westerly branch is now seen are at the 
Hill of Milleath, Drumhead, near Euthven, the Sockach [? Succoth] 
Hill, south of Glass, on the Deveron, and skirting its west bank upwards 
at Craigdornie, Craig luie, above Shenwell, Blackwater Lodge, and west 
of Creag an Sgor. A great mass forms Greer Hill of Strathdon ; it is again 
seen at Dulnein, on the Dee ; at Braemar, near the Dee ; and, according to 
MacCulloch, in the Eye Forest. 

The central band shows itself at the Eed Craig of Ehynie, the Hill 
of Tombhreac, in Auchindoir, at several points near Eedford in the 
Cabrach, on the Kindy and on the Deskry, between Morven and Cul- 
blean, in large mass at the Coyle Hills, near Ballater, and at Little 
Kilrannoch, at the head of the White Water, a branch of the South Esk. 
The eastern branch appears at Leith Hall, at Chapelton and Premnay, at 
Bourtie, Barra Hill, and Forester Hill, near Meldrum, in large mass at 
Belhelvie, and, lastly, at the Black Dog Eock, 5 miles north of Aberdeen. 

The igneous rock which appears here, and again in the vicinity of the 
great fault which separates the Old Eed Sandstone from the northern 
schists, shows itself at several places as Serpentine ; as at Cortachy 
Bridge, Balloch on the Carity ; near Barry, Hill of Alyth, and near the 
limestone at the south end of Loch Cluny : probably it is the same as 
appears north of Balmaha, on Loch Lomond. Near Kinnordy, in Forfar, 
and at Balmaha, it contains altered crystals of Enstatite. 

AYRSHIRE. At Balhamie Hill, near Colmonell, with Pseudo-En- 
statite, and near Lendalfoot, north of Ballantrae, Carlton Castle (Greg). 

Serpentinous Marbles. 

"Primitive limestones," with included patches or nodules of Ser- 
pentine, which have been derived from the serpentinisation of Malacolite 
and Sahlite, for the most part, and, rarely, of Olivine, occur in 

SUTHERLAND. At Ledbeg, colourless, and sulphur-yellow, rarely 
black. 

EOSS-SHIRE. At Totag and Beinn Chuirn, Glenelg, grey, yellow, and 
slate-blue. 

HEBRIDES. Skye, in Strath, dull yellow. Harris, at Eodil, grey, 
lona, at Port na Curaich, yellow and green. Port an Duine Mhairbh, 
yellow and grey. Tiree, Ballyphaetrish. 

INVERNESS-SHIRE. Grantown, Achnagonalin, colourless, yellow, and 
black. 

PERTHSHIRE. Glen Tilt, at Marble Lodge, yellow, pale-green, and 
grey. Cluny, dull-yellow. 

Certain substances whose nature has not been sufficiently deter-

mined, and probably in themselves mixtures, somewhat like potstone, 
have been assigned to Serpentine : as that of a dull-green colour, which 
fills rents in Logan rock at Ullapool and elsewhere, and which appa- 
rently passes into Epidosite. 

The value of Serpentine as an ORNAMENTAL STONE depends upon an 
admixture of the more precious varieties with their varying colours in 
vein and blotched arrangements, still more diversification being at times 
imparted by admixtures of Steatite, Nephrite, Marmolite, Asbestus, and 
Chlorite. 

The Unst ornamental stone is rarely fine. The most common variety 
is dark-green, with pale yellow-green veinings. In small masses a finer 
stone occurs north of Swinna Ness. This has pale-green crystals of 
softening Enstatite, impacted in a deep-green base of Precious Ser- 
pentine. The Haaf Gruney rock is pale purple, with greyish-yellow 
bands. That of Scousburgh is dark-green, with a network of pale 
yellow-green to white. 

The more westerly of the Portsoy beds of Serpentine is highly 
variegated, and, though difficult to obtain in large blocks, is probably the 
most beautiful and most variegated known. It was long wrought by a 
French company, and the pillars of the great Hall at Versailles are made 
of it. The admixture of colours of all tints except bright blues is beyond 
number. A stone with a dark green basis sprinkled with bright red 
pseudomorphs of Olivine, or of Augite, and pale-green markings, pre- 
dominates towards the west. A pale green nephritic base with interlacing 
veinings of dark-green Precious Serpentine, and nodules of pale olive- 
coloured Steatite, occurs in the centre. The Precious Serpentine is some- 
times studded with blood-red spots. Verdigris-green, with blue-black 
dendritic markings, is found at the east. The second vein, formed 
apparently by alteration of gabbro, is greyish-green, with mottling of 
dark greyish-blue. Lavender, rich brown, green and white veins of 
Marmolite, pervade the first two varieties. One vein, below water, in 
the East Bay, affords blocks of dull-green, mottled with brown, and 
is traversed by broad bands of fawn-yellow. That of the Hill of Tom- 
bhreac has a plicated intermixture of dark- and light-green, with white. 
Its appearance suggests a rock of gneissic structure as its origin. 

The Serpentine of Glen Kindy and Culblean is similar to that of 
Scousburgh. The rock at Lendalfoot is occasionally banded dark- 
green, mottled pale-green, and cream-colour, in alternate bands of an 
inch in width. 

Certain of the Serpentinous Marbles rank as ornamental stones. 
That of Glen Tilt is sap-green and sulphur-yellow, mottled with white.

The Tiree Marble is flesh-red, with imbedded granules of bright-green 
Sahlite, in every stage of alteration into Serpentine, with occasionally 
large lustrous crystals of dark Diallage. 

Other localities than these yield ornamental combinations, but in 
masses large enough only for inlaid work. At Beinn Chuirn, in Glenelg, 
snow-white with blue and green. In Tiree, white with sulphur-yellow ; 
and Ceann a bharra, and at Ballyphaetrish in Tiree ; to the east of 
which is a white marble, with lead-blue enclosures. At Leslie and Leith 
Hall the Serpentine is fibrous, as if formed from Amianthus. It is 
greyish-green, with grey and dark-blue specks, and is made into snuff- 
boxes, etc. 

155. Totaigite (481). 

[Dr Heddle at one time regarded a yellowish-brown substance which 
occurs in the metamorphic marble of Totag, Loch Alsh, and Beinn Chuirn, 
Glenelg, as a new mineral species, and described it as such (Trans. Roy. 
Soc. Edin., xxviii. 455, 1878). There is reason to believe that he sub- 
sequently abandoned this view. The mineral is now referred to Forsterite.

[Dr Heddle at one time referred one of the green compounds asso- 
ciated with the Chromite of Shetland to this species; but he appears, 
subsequently, to have abandoned this view.] 

157. Pimelite (483a). 

[Another hydra ted Magnesium and Nickel silicate, also of somewhat 
doubtful occurrence in Scotland. The substance here referred to occurs 
chiefly in the form of a rather bright ivy-green saponaceous encrustation 
upon the divisional planes of the decomposed andesitic lava of Devonian 
age, at Blackford Hill, south of Edinburgh. A mineral similar in its 
general aspect occurs also at Comrie, in Perthshire. Neither this nor 
the foregoing appears to have been analysed.]

Hexagonal ? Prasilite is in fan-shaped groups of hexagonal crystals ; 
the Sapoiiite associated with zeolites, shows under the microscope 
clusters of hexagonal crystals lining the druses, or in vermicular aggre- 
gates. It is massive or nodular when it fills the cavities. Often soft 
like butter or cheese, but on loss of water becomes granular and crumbly. 
When filling veins often transversely fibrous. G. = 218 to 2'3. Lustre 
greasy. Colour white, lavender, wax-yellow, olive-green, bluish, brown, 
Venetian red, usual colour sap-green several of these colours being 
sometimes associated in onyx-like bands. Does not adhere to the 
tongue. Some varieties fall to pieces when placed in water, often with 
a slight explosive sound.

Dunvegan Loch ; at Kudha nan Clach, brown of various shades, in onyx- 
like bands. These form the bottom of zeolitic cavities up to one and a 
half inches in thickness. The associates are Olivine and Calcite. Also 
in small druses, red, yellow, and green. At Orbost Loch, Bracadale, on 
the north shore, with zeolites. Humela Eock, south of Canna, amber- 
coloured. The rock of the east side of Scuir Dearg, Skye, rarely has minute 
cavities with an intensely-blue substance, in structure resembling Saponite. 

The following localities assigned to chlorite doubtless refer to Saponite. 
" With quartz in a felspar dyke traversing grey wacke and conglomerate, at 
Carolside on the Leader." " In amygdaloidal porphyry at Muirhouse 
law, 2 miles south-east of Maxton, Eoxburghshire." 

The following localities assigned to Steatite doubtless also refer to 
Saponite. Lanarkshire, at Phillipshill quarry, " finest in Britain, with 
zeolites." " Berwick. Dunse, near Cumledge House, in a dyke in the 
bed of the Oxenden burn, in beautiful crystals, a mineral like Steatite in 
veins, with zeolites." " In thin veins in the felspar porphyry of Lam- 
berton Hill, quarried near Nunlands." 

A study of the mode of association of Saponite with the minerals 
which occur along with it shows that the Saponite of the volcanics of 
Old Eed Sandstone and Carboniferous ages has been the substance last 
deposited in their vapour vesicles ; while that of the volcanics of Tertiary 
volcanics has been the first. 

The earliest notice of so-called Saponite gave Cornwall as its locality, 
and Cronstadt, Klaproth, and Kirwan considered the mineral there 
occurring as belonging to this species. An analysis of an exceedingly 
fine specimen specially sent the author by Professor King, of Belfast, 
showed that it was a slightly weathered vein of white precious 
Serpentine. 

A graver and more persistently indulged in error consists in petro- 
logists assigning the ever-recurring Saponite of decomposing basic and 



SILICATES. 143 

sub-basic eruptive rocks to Chlorite. This is still, by many petrographers, 
even by those occupying positions which confer the widest experience, 
referred without hesitation to that mineral. This error was pointed out 
in the year 1879 by the author, when it was shown that Chlorite and 
its congeners were confined absolutely to rocks which had undergone 
dynamo-metamorphism (see Trans. Eoy. Soc. Edin., vol. xxix. p. 101). 
On the other hand, Saponite, and what may be regarded as its congeners, 
are equally absolutely confined to eruptive rocks, which present these 
minerals as the resultants of hydro-thermal alteration. The prominent 
feature of the alteration is the pronounced hydration which accompanies 
the chemical change. The so-called " viridite " of the Car Craig Rock 
and the " Chlorite " of the Kinghorn melaphyre, figured in plate xxii. 
of Teall's British Petrography, are, in point of fact, ordinary typical 
examples of investing and vermicular Saponite such vermicular forms 
the employment of a higher magnifying power resolves into piles of 
crystals of a rudely hexagonal form. 

Though generally devoid of definite crystalline form, Saponite is 
possessed of no little interest, in virtue of the varieties of its aspect, its 
very large content of water, and the singularity of the manner in which 
it comports itself therewith. No mineral presents itself under more 
varying forms than this, as is seen in the white, clotted-cream-like 
Saponite of Quiraing the fibrous, amianthoid, lustrous, sap-green veins 
of Craigs railway cutting, in Forfar the brown, nodular, bole-like, con- 
cretionary masses of some of the so-called " Bowlingite " the blue-grey 
mottled bands, which floor zeolitic cavities, with much the appearance of 
Naples soap the diversely coloured, onyx-like variety, with its bands 
of vivid red, which is rarely seen in the rocks north of the Echoing 
Crag, Quiraing and the deep green, fan-like, lustrous rosettes of the 
"Prasilite" of Bowling. 

This solid stone contains one-fourth of its weight of water. That the 
whole of that fourth exists in it as a liquid, or in an ordinary hydrating 
condition, cannot be for a moment supposed, A certain portion must be 
playing the part of a base. But the functioning of the solid part to the 
large percentage of water given off at a temperature of 212 F. is peculiar 
in itself ; about one half of that quantity being given up at the ordinary 
temperature of the human body, and this same amount is reabsorbed by 
it, if it be placed in a moist atmosphere, so that the total water content 
ultimately is identical with that of its first composition. Now this 
extraordinary mode of functioning, as regards percentages so high as from 
six to seven, may come even to affect to a certain extent the humidity, if 
not the climate, of a locality, if any great quantity of the mineral is 
present in the rocks ; and there is a locality which, though not of great 



144 SILICATES. 

extent, is probably so affected. The peculiar vibration which is observed 
when we bring the eye close to the ground on an exceptionally warm 
day, in a locality of unusually brilliant exposure, is due to the rise of 
currents of air heated by contact with parts of the rocks affected by such 
exposure. Now a district of some miles in extent, which lies between 
Dumbuck and the Lang Crag, in Dumbartonshire, consists of a rock of 
which perhaps one-third is Saponite of a very dark green or almost black 
colour. The amount of atmospheric vibration there seen in the circum- 
stances above detailed is so great as to leave no doubt that large 
quantities of aqueous vapour are here ascending along with the currents 
of heated air. In dry, sunshiny weather the air over this district must 
be thus rendered more humid ; while in moist weather, in virtue of its 
power of reabsorbing the lost water, the atmosphere must be, to an 
equivalent extent, rendered less humid. 

FERRITE. 1 

Wallace Young, quoted by Heddle, Min. Mag., v. 28 (1882). Heddle 
(ibid., vii. 134, 1887). 

An alteration-product of Olivine in the basalt lavas of the Glasgow 
district, chiefly between Gleniffer Braes and Boyleston. It frequently 
retains the form of the Olivine crystals, but has cleavages nearly equally 
eminent, parallel to both a and b of the original Olivine crystal. It is 
soft, greasy to the touch, and of high tinctorial power, of a deep red to 
chocolate brown colour. The air-dried mineral loses 3'83 % at 212 F.

Massive, encrusting, or disseminated in small nodules, in amygdaloidal 
basalt. Fracture conchoidal. When first exposed it is translucent and 
pistachio-green or olive-green to bright amber-coloured ; but, when exposed 
to the air, changes, in the course of a few minutes, to dark brown or to 
almost black colour, and becomes opaque, splitting up in so doing into 
minute hexagonal prisms. Soft, brittle, and greasy to the touch. Lustre 
slightly glimmering. When fresh its lustre is vitreous. H., 1-5 to 2 ;

(Hullite. ) 



























Pyr., readily sol. in h. acid. 

HEBRIDES. Kum, near the summit of Creag nan Stardean (Anal. 1 and 
2), filling vapour cavities from the size of small shot to that of a bean. Of 
varying colours and appearances. The colours range from that of amber 
to malachite green. The structure at times very much resembles that of 
Malachite. All these rapidly pass, with loss of water, into black. Canna, 
on the south-west side, near a cave. The specimens here, in appearance, 
resemble cobbler's wax, and they are several inches in length. 

The occurrences noted by MacCulloch from Fifeshire do not refer to 
this substance, but are more of the nature of Hullite. The analysis of 
one from Kinkell has been subjoined above to that of the Creag nan 
Stardean mineral, in order that the difference in composition might be 
made apparent. 

KIRWANITE. 

Specimens much resembling the Kirwanite of Thomson occur in an 
exceptionally hard and tough basalt to the west of the house of Glen- 
forsa, on Loch Baa, Mull. On being sectioned, however, these proved 
to be of an entirely different nature. [This mineral appears to have 
been regarded by Dr Heddle as an undetermined species belonging to 
the same group as the following.]

Bole cannot be regarded as having any claim to be considered a 
simple mineral ; nor is it easy to say to what species it should be referred 
as an impure variety ; for that it is a mixture of two or more minerals 
there can be little doubt. Probably the substance to which the term has 
been generally applied comes nearer to Saponite than to anything else. It 



SILICATES. 149 

is probably the fact that all the substances to which the term has been 
applied in Scotland have been associated with basic eruptive rocks 
usually with basalt lavas. Of such definite application we do not find, 
perhaps, so many in Scotland as in England. We find Greg (p. 442) 
giving as localities " in sandstone at Quarry Wood, Morayshire, and 
Bridgehouse in Peeblesshire," and the present writer has heard the name 
applied to some of the brown Saponite of Bowling ; the fact of the sub- 
stance falling to pieces in water seemed to be its only characteristic 
property.

An amorphous, hydrous Aluminium Silicate. Usually botryoidal and 
reniform. Fracture conchoidal ; brittle. H., 3 ; G. 18'2. Pellucid, 
vitreous. 

A mineral referred by Dr Heddle to this species occurs at Kings 
Laggan Mine, Lauchentyre, Kirkcudbright, in the form of a dull earthy 
encrustation, which coats quartz in one of the lead veins there. Chryso- 
colla and Pyromorphite occur with it.] 

[i66. Plinthite. 

A dull-red, earthy material, somewhat botryoidal in form on the 
weathered surface, and with a greasy lustre, sometimes earthy ; is found 
in connection with the Tertiary basalt lavas of the parts of Skye near the 
Quiraing and the Storr Eock.] It falls to pieces in water, and by this and 
its uniformly dense structure it may be distinguished from red Mesolite.

152 SILICATES. 

SHETLAND. Colla Firth, south side, in Potstone, like felt (D. and H.), 
possibly only a matted Amianthus. 

BANFFSHIRE. Mouth of the Burn of Boyne. In limestone, in thin 
leaves, leather-like (Anal. 1), and like cork or the roots of trees. With 
Pyrites, Calcite, and Steatite. Near Portsoy, in Serpentine (Jameson) 
Anal. 5. In the Cabrach. In the west bank of the Burn of 
the Cairn, a short distance above its junction with the Ronster Water. 
In rifts of a decomposing granite in large sheets like cork Anal. 6. 
Burn of Craig, north of Tombhreac. In the Burn of the Daugh 
(Hinxman). 

HEBRIDES. Skye. Loch Bracadale, at Sgurr nam Fiadh. In druses 
on Analcime. Associated with Scolecite, Stilbite, Chabasite, Mesolite, 
Laumontite, Calcite. Filamentous, and like scum. 

ARGYLLSHIRE. Strontian. In the calcareous gangue of the Galena, 
like leather Anal. 3. 

KINCARDINESHIRE. At the Tod Head. In Old Eed Sandstone 
conglomerate, in a calcite vein, with cockscomb Barytes, which penetrates 
the Pilolite upon one side. The mineral here is like both cork (Anal. 7) 
and leather (Anal. 2). 

FORFARSHIRE. In the railway cutting near Craigs, as thin filaments 
in the centre of amygdaloidal druses. Colour brownish-white; some- 
times like scum. 

FIFESHIRE. In the railway cutting near Tayport on the west. 
It forms a coating like floss-silk to one side of veins of Calcite, in 
amygdaloid Anal. 8. Colour pure white. Associates, Natrolite, 
Barytes, and zeolitic Quartz. Similarly, in small druses near Auchter- 
muchty. 

LANARKSHIRE. At Leadhills. (Wanlockhead, Jameson). In calcareous 
veins in Ordovician rocks (Jameson) Anal. 4. 

BERWICKSHIRE. In veins in greywacke, near Kelso (Eeid, Geo. 
Gunn, and Goodchild). 

This singular substance used to find a place amongst the varieties of 
Hornblende. How previous authors, and how Dr Thomson, and others 
who analysed it, could place a substance which contained 23 % of water 
along with one which is anhydrous is not easily explained. Had these 
analysts gone into the detail of ascertaining the amount of that water 
given off at 212 F., it would have been still more unaccountable. 

It is a substance peculiar also both as regards the features of its 
occurrence and the wide range in lithological character of the rocks in 
which it is enclosed. 

As regards its appearances, we find it assuming the character of felt ; 



SILICATES. 153 

in leather-like leaves; resembling cork or the roots of trees; forming 
large sheets, which, in virtue of its altogether unrivalled toughness, 
would have served for the targe of a Highland warrior ; in tufted filaments 
with zeolitic associates ; a scum which appears to have sedimented from 
suspension in a muddy liquid, and simulating the very finest floss silk. 

As regards the parent rocks, these include Serpentine, Granite, Con- 
glomerate (Old Eed), Andesitic lava, Basalt lava, associated with Gneiss, 
and in Ordovician Argillites. 

Its associated minerals accordingly are equally diverse. Those with 
the limestone matrix are Pyrites, Calcite, and Steatite ; those of the 
Andesites are Calcite and cockscomb Barytes (the crystals of which 
penetrate the Pilolite), at one locality ; Analcime at another ; and 
Natrolite, Barytes, and zeolitic Quartz at a third. Those of the basalts 
also comprehend a wide range of minerals Analcime, Scolecite, Stilbite, 
Chabazite, Mesolite, Laumontite, and Calcite. 

[173. Pihlite. 

Now regarded as a mechanical mixture of Muscovite and a felspar. 

There is one specimen of thermo-inetamorphosed argillaceous mica 
schist from Clova, Aberdeenshire, in the Scottish Mineral Collection, 
which has been referred by Dr Heddle to this species.]

SILICATES. 



Crystals vary extremely in form, being generally apparently oblique, 
tabular from predominance of the face v y which are hemidomes in alternate 
position on opposite ends ; also, but more rarely, prismatic, with dominance 
of I and (M.). Twins frequent. Twin face c (a), and formed by revolution 
of either a or an axis normal c (a), or & on a vertical axis. The former 
is very common, and usually produces thin tabular crystals with a re- 
entering angle along one side, and sometimes elongated. It occurs 
occasionally in double twins. Sometimes it is granular or foliated. Cl. 
in some c (a), I, n, in others r (m). H., 5 to 5*5 ; G., 34 to 3*6. Semi- 
transparent ; lustre adamantine to resinous. Colour yellow, brown, and 
green. B.B. fuses with microcosmic salt in the reducing flame, and gives 
a reaction for titanic acid.

Collie, " On Some Leadhills Minerals," Journ. Chem. 8oc., Iv. p. 94, 
describes a mineral from Leadhills under the above name. It occurs in 
black botryoidal masses, and is unlike either Pyromorphite or Vanadinite 
in appearance. The fracture is uneven or conchoidal; it fuses easily 
before the blow-pipe, leaving a brown granule, which, when broken, 
shows a crystalline structure. It dissolves readily in hydrochloric acid 
when warm, and leaves a slight residue of a brown colour, which consists 
chiefly of an oxide of iron. Two analyses were made :

Comp., Phosphoric acid, 35'2 ; Alumina, 38 ; Water, 26'8. 

Principally at Garbh Eilean, the largest of the Shiant Isles, where 
the writer of this note has found it on the north shore, close to Sgeireaii 
a' Bhaigh. It occurs in the form of discoidal aggregations of radially- 
disposed acicular crystals, coating the joints of one of the Middle 
Jurassic clays, close beneath the base of a thick intrusive sheet of 
dolerite of Tertiary age, and highly indurated by the contact. An 
orbicular structure has been developed in the clay by the contact 
metamorphism, and a note on one of the specimens in the Scottish 
Mineral Collection states that the author regarded the Wavellite as 
forming the basis of the spheroids referred to. 

In the article " Mineralogy," in the 9th edit, of the Encyclopaedia 
Britannica, the author refers to this species a mineral occurring in the 
form of contiguous groups of thin discoidal aggregations of acicular 
crystals, which coat the joint faces of one of the andesitic la*vas of 
Devonian age in Glencoe. A specimen of the mineral referred to was 
placed with the Wavellites in the Scottish Mineral Collection ; but the 
author left no further information regarding it than the statement that 
the specimen is in the near neighbourhood of Withamite. Wavellite 
usually occurs on the joint faces of fossiliferous rocks of argillaceous 
composition, which have been affected by contact metamorphism 
(J. G. G.).]

sketches left by the author.] 

As the consideration of Linarite concludes that of the special 
Leadhills minerals, the following statements as to their local occur- 
rences and special associates fittingly find a place: 

CERUSSITE. 

Is associated with Leadhillite, Lanarkite, etc., in the Susanna Mine. 
Also in the mines of the Leadhills Dod, with Linarite, Leadhillite, and 
Pyromorphite. Also in the Wanlock Head Mines generally -sometimes 
with Blende, but generally with Galena, and on Quartz. 

ANGLESITE. 

Frequent in Susanna Mine. Not so in Leadhills Dod in Galena, 
covered with Pyromorphite, the Anglesite being in cavities of the 
Galena. Its associates are, in Susanna Mine, Lanarkite, Linarite, and 
Cerussite. In Wanlock Head Mines it occurs per se. 

LINARITE. 

In the Susanna Mine, its associates being Anglesite, Caledonite, and all 
except Susannite. In the Leadhills Dod it occurs with pointed Lead- 
hillite, associated with Cerussite, Caledonite, Chrysocolla, and Malachite. 
In the Wanlockhead Dod, in the Belton Grain Vein, and in the High 
Pirn Mine, with Caledonite, Chrysocolla, and Tile Ore. Also in the Bay 
Vein, with flat, nailhead Calcite, Cerussite, Wad, and Leadhillite. Lately, 
in small crystals, with new faces, at the Glengonner Shaft. 

LEADHILLITE. 

Occurs at all the Leadhills and Wanlockhead Mines, except the Belton 
Grain Vein. At the Leadhills Dod it occurs only in acuminated crystals, 
apparently Mefv: also in larger crystals with the P face, its associates 
being Caledonite, Chrysocolla, and Cerussite. 

LANARKITE. 
Occurs only in the Susanna Mine. 

CALEDONITE. 

In the Susanna, Leadhills Dod, and the Belton Grain Vein of the 
High Pirn.

PYROMORPHITE. 

At the Susanna Mine and Leadhills Dod, and the Wanlockhead Dod ; 
the orange being fine only in the Susanna Mine, but a bright sulphur- 
yellow occurring in the Wanlockhead Dod. 

VANADINITE. 

At the High Pirn Mine ; but also at the Leadhills Dod, with Silicate 
of Zinc, being there crystallised in orbicular groups. 

200. Gypsum (746). CaS0 4 +2H 2 0.

brown, and more rarely greenish or bluish. Heated in the closed tube 
yields water. B.B. becomes white and opaque, and finally melts into a 
white enamel. Soluble in 400 to 500 parts of water; scarcely more so 
in acids. At a temperature of about 140 C. the water of crystallisation 
is driven off, and the assay becomes friable.

finally black, becoming magnetic. Gives the reaction for iron with 
fluxes. Soluble in twice its weight of water, and the solution is 
blackened by a tincture of nutgalls. 

BENFREWSHIRE. Hurlet [and many other localities. It usually 
occurs as an efflorescence on artificially-exposed shale containing

Water, 467. (Dana, 6th ed., p. 954.) 

An analysis by Dr Thomson, of a specimen from Hurlet, closely 
accords with the above. 



182 SULPHATES, ETC, 

Greg & Lettsom (Brit. Min., p. 274) state, "This salt occurs 
abundantly in the shale of exhausted coal beds at Hurlet and Campsie, 
near Paisley." [Similar conditions to these existing at those localities 
are to be found at other places in Scotland, and therefore Halotrichite 
is probably of commoner occurrence than has been supposed.]

HYDROCARBON COMPOUNDS. 185 

[HATCHETTITE. 

Under the name of Mountain Tallow this substance was recorded in 
1824 from a bog on the borders of Loch Fyne by Brande, Edin. Phil. 
Journ., xi. It has not been analysed. Dana, 6th ed., p. 997, states 
that this substance "is probably identical with the kind of paraffin 
that fuses at 45 cl -47 C. ; and which has been obtained by the destruc- 
tive distillation of Boghead Coal and peat, and from other sources."]

GUAYAQUILLITE. 

LINLITHGOWSHIRE. Bathgate, in the centre of ironstone nodules, in 
Lower Carboniferous rocks. In the JEdin. Phil. Journ., second series, 
vol. xv. p. 398, we read: " Antediluvian Ambergris. In the clay iron- 
stone of our coal formation, near to Bathgate, Burntisland, etc., we have 
been long familiar with a pale, yellowish-white and wine-yellow, trans- 
lucent, soft, inflammable mineral, to which no particular name has been 
given. It is now said to have the characters of ambergris." The pre- 
sent author has two specimens of this ; and a specimen identical with 
these in appearance, in the Gallery of Scottish Geology and Mineralogy 
in the Edinburgh Museum of Science and Art, has the foregoing notice 
attached to it. Though no analysis has been made, the physical pro- 
perties quite agree with those of Guayaquillite.

AYRSHIRE. At High Blantyre, in limestone. In the Dairy lime- 
stone, at Glen Cart. On the Lugar. 

TORBANITE. 

[Torbanite, although related to Cannel Coal, has a very nearly 
uniform composition, according to all analyses thus far made, excepting 
that of Miller, and this composition is like that of Bathvillite, but with 
less oxygen. It corresponds very nearly with the formula C 40 H 68 2 . 25 = 
carbon, 8219 ; hydrogen, 1148 ; oxygen, about 6'0 ; nitrogen, T37 = 100 : 
excluding the nitrogen, C., 82-28 ; H., 11-54; 0., 6'08 = 100. Less than 
1J % of Torbanite is soluble in naphtha (Fyfe). From Dana, Syst. Min., 
6th ed., p. 1009. 

In Upper Carboniferous rocks, at Torbane Hill, Bathgate parish, 
Linlithgowshire. 

" It frequently occurs in seams of some considerable size, and always 
in the neighbourhood of coal, sometimes in immediate contiguity with it, 
but at other times . . . separated from it by a layer of fireclay." The 
colour varies from tan colour to sooty-brown. Its fracture is dull, and 
often conchoidal, like that of cannel coal, and it is translucent in thin 
section. "Its specific gravity ranges from 1'2 to 1-3." Its streak varies 
in colour from saffron to umber, and is usually shining, and very similar 
to that afforded by oil shales. " It is tough, and not so brittle but that 
thin sections may be made of it." It possesses considerable elasticity, 
and, " when struck by the hammer, it emits a dull sound. The remains 
of plants, especially of Stigmaria, are of constant occurrence, and can be 
distinguished by the naked eye without difficulty. . . . Under the micro- 
scope it is found to consist of masses of a yellow material, some being of 
irregular figure," spores and spore cases, " others more or less rounded, 
embedded in a granular matrix, which vary in colour from a yellowish- 
brown almost to a black." (The sections in quotation marks are from a 
paper by Professor Queckett, On the Minute Structure of . . . Boghead 
Cannel Coal, pp. 34-36, 1853 ; the others by J. G. G.) 

Dr Eedfern, Micro. Journ., iii., and Rep. Brit. Assoc., 1854, states, 
regarding its mode of occurrence : " It has a layer of cement stone 
immediately above it, half an inch to two inches in thickness. Above 
that is a bed of shale, varying in thickness up to four feet. Immediately 
below the bed is a stratum of fireclay, with occasional ironstone balls, 
about two inches thick, and very full of impressions of plants. Under 
that is a layer of good bright-looking coal six inches in thickness.

Occasionally a thin layer of common coal of variable thickness runs 
right through the Boghead Mineral." 

With reference to the composition of Torbanite as compared with 
Scottish (and other) coals, the following tables of analyses, given by 
Professor Fyfe, Journal of the Royal Scottish Society of Arts, iv. pp. 250- 
266 (1854), may usefully be reproduced here] :

SUPPLEMENT. 

BY J. G. GOODCHILD. 



IN the course of printing the Mineralogy of Scotland, it has been found 
that one or two species have been accidentally overlooked. Besides 
these, there were some few other species regarding the validity of which, 
there is reason to believe, the author's views had changed. Others were 
of doubtful authenticity as occurring in Scotland. Then, again, during 
the last three years, a few species have been added to the Scottish list, 
chiefly by the officers of the Geological Survey. To these species must 
be added those already known as Scottish, which have lately been dis- 
covered in new localities. Finally, the Editor has been continuously at 
work during the last three years at the arrangement of the Scottish 
Mineral Collection in the Edinburgh Museum of Science and Art. In 
the course of this work he has determined a large number of forms, and 
has made drawings of several hundred combinations. The crystals so 
drawn are all indicated by blue pointers, are all duly registered, and are 
placed so that the public can easily study them, and the drawings are 
exhibited in contiguity to the specimens. The results of some part of 
this work are given in the notes that follow, in which the symbols 
employed are all Dana's (sixth edition), and the Museum reference 
numbers are given in prefixed brackets. 

The Editor is responsible for all the following statements, except 
where it is stated to be otherwise. 

EDINBURGH, November, 1900. 

Diamond (1). 

Localities. On the ticket of a specimen found by Dr Heddle, and 
given to Mr Thorns shortly before his death, and now in Mr Thorns' 
cabinet, is as follows: "This specimen of Aventurine, from a lake 3 
miles to the north-east of Ben Hope, Sutherland, contains, besides the 
red mica, red Zircons, and either colourless Garnets or Diamonds." 
VOL. II. N 



1 94 SUPPLEMENT. 

In handing this specimen to me, however, Dr Heddle remarked that 
in his own mind he felt confident that these small crystals were 
Diamonds, as they had certain optical properties which no other 
mineral he knew of possessed. 

Although not alluded to in the manuscript of this book, it is judged 
advisable to place this on record (A. Thorns). 

Graphite (2). 

Close examination of the minerals occurring in the various meta- 
morphic limestones occurring amongst the Highland Schists and Gneisses 
has brought to light the fact that scales of Graphite are present 
in nearly every case. A conspicuous example is presented by the 
limestones of Glenelg, described by Mr Clough (Q.J.G.S., Iv. 372). 
Probably some, at least, of the supposed Molybdenite recorded from 
the metamorphic marbles of Scotland will prove to be really Graphite. 

Sulphur (3). 

Crystallised Sulphur has been found as a product of the spontaneous 
combustion of Lower Carboniferous shales containing Pyrites, at several 
places in Scotland. It would seem to be almost as much entitled to rank 
as a native species as most of the Nitrates and Hydrous Sulphates. 

Bismuth (11). 

This is mentioned by Greg, Brit. Min., 378, as occurring formerly at 
Alva, in Stirlingshire ; reticulated and associated with Erythrine. 

Gold (13). 

Small specks of Gold have lately been detected in various eruptive 
and metamorphic rocks from Scottish localities. Probably, in a very 
sparsely distributed state, its occurrence may prove to be much more 
general than has hitherto been supposed. 

Greenockite (68). 

The Editor has examined and drawn a large number of crystals of 
Greenockite, almost the whole of which are characterised by complex 
oscillatory combinations of the prism (1010) with various pyramids, 
chiefly (1011), (2021), and (1012); all appear to be hemimorphic, and 
all show more or less want of symmetry in regard to the relative sizes of 
the faces of each form. The figures by Miigge, Jb. Min., ii. 18, accu- 
rately represent the general habit of the Scottish crystals, and Dana's 



SUPPLEMENT. 195 

description of the morphology of Greenockite (Syst. Min., sixth edition, 
p. 69) embodies the results of Miigge's investigation of that species. 

Pyrrhotite (74). 

Like Graphite, this mineral proves to be an almost constant associate 
of limestone in the Highland Metamorphic Series ; it is of common 
occurrence also in the accompanying epidiorites. 

Pyrite (85). 

ARGYLLSHIRE. Strontian, a, ao, and botryoidal. Strachur, in Mica 
schist, in small quarry behind village, a. Onich, in old slate quarries, 
nickel replacing part of the iron, in large quantities, the crystals 
decomposing on exposure to the atmosphere (A. Thorns). 

Rammelsbergite (100). 

This mineral is stated, by Dr Heddle, on one of the tickets in the 
Scottish Mineral Collection in the Edinburgh Museum of Science and 
Art (602.3), to occur in connection with Niccolite and Dudgeonite at 
" Menimuir Burn, Cassencarrie." 

Bruiachite (175). 

Noticed by T. D. Wallace (Min. Mag., vi. 169) and described by 
Macadam (Min. Mag., vii. 42) from Loch Bruithaich, Inverness-shire, 
shown by Heddle to be identical with Fluor (Min. Mag., viii. 274). 

Amethyst (210). 

Occurs lining the vapour cavities in the upper of the two basic 
intrusive sheets at Hound Point, Dalmeny, Firth of Forth, and also 
forming small amygdules in a dyke traversing the red rocks below the 
new promenade west of Dunbar ; the same rock may be traced westward 
as far as the rifle butts on the east side of Belhaven Bay. 

Quartzine (210 A). 

A fibrous form of crystalline Si0 2 ; supposed to be the cryptocrys- 
talline constituent of Chalcedony, and therefore present in all Agates. 

Agate (210). 

Many new localities for Agates in Scotland have been discovered 
while the present book was passing through the press. Almost without 
exception they are from vesicles in rocks of sub-basic composition mostly 
from Augite Andesites. Mr E. Dykes has collected them from the 



196 SUPPLEMENT. 

Devonian Andesites of the Ayrshire coast and from the Pentlands ; 
Mr Benjamin Brown from the same rocks near the foot of the lower 
reservoirs in the Pentlands; Mr J. Bisset from the same rocks at 
Connel Ferry ; Mr Kobertson and Mr Mears from Arthur's Seat ; the 
Editor has obtained them from Devonian Andesites, among other places, 
at St Abb's Head, various localities on the Scottish flank of the Cheviots ; 
from ? Andesitic lavas of Lower Carboniferous age at Jovis Neuk, 
N.E. of Aberlady Bay, etc. 

Veins of Chalcedony occur traversing the dolerite of Hawk Crag, 
Aberdour, and also that of Burntisland. 

Molybdite (219). Mo0 3 . 

" At Mount Coryby near Loch Creran in Argyllshire ; and at East 
Tulloch, south of Loch Tay, in Perthshire, according to Heddle " (Greg 
and Lettsom, Brit. Min., p. 348). 

Tenorite (230). 

In the Scottish Mineral Collection there is a specimen from Leadhills, 
which has been regarded as a pseudomorph of this species after Galena. 

Corundum (231). 

An account of the geognostical relations of Corundum (in Scotland 
and elsewhere) is given by Teall in his Presidential Address to the 
Geologists' Association, " The Natural History of Cordierite and its 
Associates" (Proc. G-eol. Assoc., xvi. 2, pp. 61-74). In this, Mr Teall 
describes the occurrence of Corundum in minute crystals in thermo- 
metamorphosed schists from the neighbourhood of the Cruachan diorite- 
granite. " The Corundum in this rock occurs in crystals and more or 
less irregular grains. The crystals are combinations of the hexagonal 
prism, the primitive rhombohedron, and the basal plane. They are 
sometimes flat and sometimes prismatic. The flat forms, in which the 
prism is feebly developed, are frequently stepped on the basal plane, 
owing to the repeated alternations of this face with the faces of a rhom- 
bohedron " (op. cit., p. 64). 

Mr Thorns sends the following note : 

"White Sapphire" of Tiree, or Corundum, was first mentioned by Greville, T.R.S., 
1798, whose description was quoted by Jameson (vide his Scottish Isles, ii. 33), but 
this identification was almost at once abandoned and the true nature of the mineral 
was recognised at least as early as 1817 by Sowerby. Dr Heddle also refers it to 
Malacolite in his last Chapter, confirming Sowerby. 



SUPPLEMENT. 19? 

Haematite (232). 

This appears to be, in the great majority of cases, a vestigial product 
from one or other of the Eed Eocks usually from the New Red. It 
therefore occurs here and there over the greater part of Scotland which 
is not occupied by rocks of later date than the New Eed. The Editor 
has discussed this view of its geognostical relation in several papers, 
especially in " The Genesis of Scottish Minerals " (Proc. Roy. Phys. Soc.), 
and "Haematite on Arthur's Seat" (Trans. Geol. Soc. Edin., 1900). 



Ilmenite (233). 

Dr Heddle always distinguished between Iserine, which is the form 
occurring in connection with basic eruptive rocks (which forms much 
of the iron sand) and Ilmenite, which is confined to dynamo- 
metamorphosed rocks. This distinction appears to be a very useful 
one, and is thoroughly borne out by the facts. Nearly all the specimens 
of Ilmenite proper occur in connection with Quartz veins, and are 
associated with one or more members of the Chlorite Group. 



Spinel (234). 

Mr Teall's paper, above referred to, mentions the frequent occurrence 
of Spinel in thermo-metamorphosed rocks. Mr C. T. Clough has lately 
presented to the Edinburgh Museum a fine series of Spinels from the 
metamorphic marble of Glenelg, in which this mineral is associated 
with Diopside, Tremolite, Forsterite, a light mica (usually regarded as 
Phlogopite) Crystalline Graphite, and other minerals (see Clough and 
Pollard "On Spinel and Forsterite from the Glenelg Limestone," 
Q.J.G.S., Iv. 372), in which these occurrences are described, and from 
which the following analysis is taken :

Minium (244). 

It is stated by Greg (Brit. Min., 388) to occur at Leadhills. There 
is a specimen so labelled in the Scottish Mineral Collection from that 
locality, which was regarded by Dr Heddle as belonging to this species. 
It resembles an impure Liinouite. 



198 SUPPLEMENT. 

Psilomelane (269). 

Omission was made in the text of reference to the fine coloured 
figures of the Hoy Psilomelanes, which have been added to the illustra- 
tions. 

Oalcite (270). 

A considerable number of beautifully crystallised specimens of 
Calcite, embracing a great variety of combinations, is to be found in the 
Scottish Mineral Collection. The majority of these do not appear to 
have yet been published. Freehand drawings of about two hundred 
specimens, of which the forms have been determined while the present 
work was passing through the press, have been made by the Editor, and 
are placed next the specimens to which they refer. 

Hydroplumbite (269). 

Heddle (Min. Mag., viii. 201). In minute, crystalline scales (hex- 
agonal), forming thin, white, flakes with pearly lustre, soluble in nitric 
acid, the solution showing the presence of lead alone. B.B. yields water. 
Inferred (but on very insufficient grounds) to be 3PbO.H 2 0. Observed 
with Cerussite and Pyromorphite upon Galena. Locality doubtful, or 
perhaps from Cumberland or Leadhills. (Taken from Dana, 6th edition, 
p. 259.) 

Smithsonite (275). 

LOCALITIES: Dumfriesshire; Wanlockhead. (A. Thorns, on the 
authority of Dr Wilson of Wanlockhead.) 

Witherite (279). 

It may be well to note here that all attempts at finding Witherite 
at any Scottish locality have hitherto failed, although Barytes is one of 
the commonest minerals in the country. 

Orthoclase (313). 

AYRSHIRE. The feldspar obscurely crystallised in geodes in the 
microgranite of Ailsa Craig much resembles Murchisonite, and is, no 
doubt, a soda-orthoclase, as suggested by Teall. (James Currie.) 

Attention may also be directed here to a paper by Mr Currie " On 
the Feldspars of Canisp " (Trans. Geol. Soc. Edin., vii. 494) in which the 



SUPPLEMENT. 199 

geognostic relations of this and the associated Albite are described, and 
with which is given a figure of crystal twined on m (110). 

Dr Flett, in the same journal (p. 482), has also described some in- 
teresting phenocrysts (or insets) of micropegmatite occurring in a mass 
of microgranite of Devonian age at Black Hill in the Pentland Hills. 



Microcline (315). 

(Additional notes supplied by James Currie.) 

Flannan Islands, nacreous, white (MacCulloch). 

ST KILDA. In drusy cavities in the Syenite, imperfectly crystallised 
and with Smoky Quartz (MacCulloch). 

" The Feldspar of the red granite of the Eoss of Mull is described 
by Haughton as Orthoclase : but as his analysis of the granite shows 
almost equal quantities of potash and soda, it would seem that the 
feldspar is a Microperthite and most probably a Microcline-Microper- 
thite." 

The waxy-lustred variety of Microcline occurs near Birse, micro- 
graphic and associated with Andesine, Apatite, and Sphene. 

Soda-Microcline (315A). 

Microscopic examination by Mr James Bisset and Mr Andrew 
Stenhouse of the large ejected fragments of feldspar included in the 
agglomerate and other eruptive rocks on the shore between Elie and 
St Monance in Fife, has shown that they consist of polysynthetic twins 
of a triclinic feldspar. This confirmation of a view which many persons 
have long held, following Dr Heddle's analysis (q.v.) t seems to justify 
the reference of this mineral to Socla-Microcline. Probably this 
mineral will eventually prove to be of much commoner occurrence in 
Scotland than has hitherto been supposed. Fine specimens from the 
localities mentioned, as well as from the east of Fife, are placed in the 
Scottish Mineral Collection. 

Dr Heddle gave considerable attention to the vitreous and lithoidal 
states of eruptive rocks, and collected a fine series, which he placed with 
the Feldspars when he was arranging the Scottish Mineral Collection. 
Amongst these are fine examples of Pitchstone from almost every 
known Scottish locality, as well as equally fine specimens of Tachylite. 
His examples from Loch Scridain, Mull, formed the subject of a paper 
read before the Glasgow Geological Society (vol. x. pp. 80-91). With 
these are placed examples of Petrosilex and Petuntze, from Black Hill, 
Pentlands.

ORKNEY. Sanday, near Saville, in a large boulder (probably a 
Norwegian erratic), white, penetrated by Actinolite, with Hornblende, 
Apatite, etc. Stack and Skerry, west of Hoy, in belts in the gneiss, 
with sericitic gneiss (James Currie). 

Leucite (321). 

Eegarding this mineral, it may be remarked that all the Analcimes 
which have yet been found in Scotland appear to be secondary products, 
and formed within pre-existent cavities within the rock in which they 
occur ; and no British example yet known affords any good reason for 
regarding Analcime as a replacement or pseudomorph of pre-existent 
Leucite. 

Augite (325). 

The bright green variety of Augite known as Omphacite occurs in 
a few localities in Scotland as a constituent of the Garnet-Amphibole- 
Pyroxene rock called Eclogite. Messrs Teall and Clough have lately 
described such from J mile KE. of Loch Coir' an Daimh, 2 miles N.E. 
of Glenelg. (See also Teall, Min. Mag., ix. p. 217.) 

It may be remarked here, that distinctly-terminated crystals of 
Scottish pyroxenes are of rare occurrence in collections. The Heddle 
Collection includes only three such of Diopside, none of which appear 
to have been yet figured. Crystals of Augite weathered out of the 
Arenig tuffs at Sanquhar, Dumfriesshire, have been obtained by Mr 
Macconochie. The combinations are the usual ones of a, 100 ; I, 010 ; m, 
110; and s, 111, the latter forms nearly all shewing strongly-concave 
surfaces. Except in the idiomorphic Augites abundantly present in so 
many basic eruptive rocks, these four occurrences represent all that 
are in the Scottish Collection. 



SUPPLEMENT. 201 

Most of the Diopsides occurring in Scotland are distinctly minerals 
of secondary origin, developed within marbles by thermo-metamorphic 
action. Only in very rare cases do they shew crystalline termina- 
tions although they are all idiomorphic in the prismatic zone. 

^Egirine (326). 

Mr Teall has detected ^Egirine in an intrusive rock allied to 
Borolanite from the Coigach district of West Eoss-shire. It occurs in 
long prisms, idiomorphic in the prismatic zone, and is associated with 
Biotite, Orthoclase, Nepheline, Melanite, etc. 

Mr Cunningham Craig also records ^Egirine in granulitic rocks 
from Glen Lui, Aberdeenshire ; 65 N.W. 

Spodumene (327). 

In one of Dr Heddle's note-books is a record of the occurrence of this 
mineral " in an east and west quartz-porphyry dyke which cuts the north 
slope of the Cairnwell just above the col between it and Cairn Geodch 
and overlooking Loch Bhrotichan." 

Wollastonite (329). 

Amongst other localities where this mineral has been detected 
mention may be made of its occurrence in the Borolanite of the neigh- 
bourhood of Inchnadamff, where its existence was made known by Mr 
Teall (Trans. Eoy. Sue. Edin., xxxvii. p. 175.) It is associated with 
Orthoclase, Melanite, Nepheline, etc. 

Rhodonite (335). 

A mineral bearing a strong external resemblance to Ehodonite occurs 
in the metamorphic marble of Dalnabo, Glen Gairn, Aberdeenshire. Dr 
Heddle has, however, shewn that this is really the variety of Sphene 
known as Greenovite, see Dufrenoy, Ann. des M. 3rd, xxii. 529. 

Amphibole (338). 

Tremolite. 

INVERNESS-SHIRE. About a quarter of a mile above Eoy Bridge, in 
the bed of the river, in Muscovite schist, with Garnets, some of the 
crystals over five inches long. Scourvang Hill, south of Fort William, 
in limestone. Kirnish Burn, south of Fort William (A. Thorns). 



202 SUPPLEMENT. 

Hornblende. 

INVERNESS-SHIRE. Fort Augustus railway cutting, below the Free 
Church, Gairlochy, in terminated crystals, m clr n. In Shingang Burn, 
in Hornblende schist, about two miles east of Banavie (A. Thorns). 

Beryl (344). 

Most of the Scottish Beryls in the Collection at the Natural History 
Museum in the Cromwell Eoad, London, as well as those in the Edin- 
burgh Museum of Science and Art, are quite devoid of any crystalline 
terminations (as they are allotriomorphic along (c) to other minerals). 
A very few, only two in the Edinburgh Museum (344 8-9), are termin- 
ated, and these are enclosed within dark Cairngorm. They shew the 
combination m cp and a very rough form, which appears to be r. They 
are stated to be from the Cairngorm Mountains. The terminations on 
all the others are in some cases fractures, in others they are impressed 
faces from minerals associated with them, especially from Quartz, while 
in the remainder these surfaces are due to etching by natural solvents. 

Sodalite (362). 

Mr Teall, Trans. Roy. Soc. Edin., xxxvii. pt. 1, No. 2, p. 175, records 
the occurrence of an alteration product after a mineral belonging to the 
Sodalite Group, in the rock Borolanite, from the neighbourhood of 
Inchnadamff, Cnoc na Sroine, Loch Borolan, and Ruighe Cnoc, Sutherland 
& Eoss. It is associated with Orthoclase, Nepheline, Melanite, etc. 

Garnet (370). 

Amongst the fine series of Garnets in the Scottish Mineral Collection 
are some remarkable crystals from Knock Hill, 4 m. N.E. of Grange 
Station, Banffshire; 86 N.W. On the d faces of these an oscillatory 
combination of d r s builds a step-like face looking somewhat like a low 
pyramid.

Olivine (376). 

(Supplementary notes by Mr James Currie.) 

SUTHERLANDSHIRE. An arrowhead twin from Lairg which had the 
appearance of Keilhauite, proved, on analysis, to have much the com- 
position of Olivine (see Analysis 3, p. 51, vol. ii.). 

HEBRIDES. In the gabbro of the Cuillins (Zirkel). At Camus 
Daraich in Sleat, in microscopic crystals, o n k (Clough and Harker), at 
Dun vegan (MacCulloch). 

Olivine is found replaced by Prehnite at Dumbarton (Allport), but 
more usually it passes into Haematite on the one hand or Serpentine on 
the other. Examples of the former change occur at Duncarnock in 
Lanarkshire, Bowling (Allport) and Calton Hill (Tschermak). Serpentine 
with the form of Olivine is found at Bowling, Mugdock, Arthur's Seat, 
and jtfeilston (Allport). Sometimes the centre of the grains is unaltered 
Olivine ; sometimes it is Serpentine surrounded by Haematite. 

An intermediate stage in the transition to Haematite is shewn by the 
pseudomorph to which the name Ferrite was given by Mr Wallace 
Young. This occurs at Kilpatrick, at Gleniffer Braes (J. Young), and at 
Boyleston (H.). At the last locality it occurs in the form of Olivine 
with the combination a I c d e (as in fig. 4 Anal). It is remarkable 
that though Olivine of two quite diverse habits is found at this place, it 
is altered into Ferrite only when it occurs in the form mentioned.

Phenacite (382). 

" A crystal almost identical in appearance with the Uraliau phenakite, 
was found by Dr Heddle at Hillswickness Point, opposite the Drongs in 
Shetland. The crystal is embedded in mica slate, so that the faces are 
rough ; it may be merely beryl." Greg & Lettsom's Brit. Min., p. 473. 

Scapolite (387). 

This has been recorded by Mr Cunningham-Craig from calc-silicate 
hornfels from Altt an t' Sionnaich, Aberdeenshire ; 65 S.W. Mr Clough

records it from some Argyllshire localities, and from near Cnoc na h'Ula, 
near Laxford, and also from near Shieldaig, Gairloch. 



Idocrase (393). 

Amongst the specimens of this mineral from the metamorphic marble 
of Dalnabo, now in the Scottish Mineral Collection, are (393*8) shewing 
the combination a m hfp c ; (393*13), a m hfc ; (393*20), a m hfcp e u. 



Zircon (394). 

Amongst the Zircons in the Scottish Mineral Collection are two from 
" Brann a'Bharra " which occur in pegmatite, and shew the combination 
mxp (on 394/9) and maxp (on 394/10); (394/4) from Beinn Bhreac 
mpvu. 

Danburite (396). 

Dr Heddle at one time regarded the brownish-yellow serpentinous 
mineral occurring in the Glenelg marble as possibly pseudomorphous 
after this species. See also Totaigite, Chondrodite, Forsterite, etc. 



Topaz (397). 

The collection of minerals in the Edinburgh Museum of Science and 
Art contains a good series of crystallised specimens of Scottish Topaz, 
none of which appear to have been either figured or described. They 
have no localities attached to them ; but there is some reason to believe 
that they mostly came from the granite area to the north-west of 
. Invercauld, Aberdeenshire. The Editor has examined and drawn most 
of these. The combinations include the following: (O.M.C., 27) ml n 
dofyf$\ (397 17), modvf, with a broad surface formed by the basal 
cleavage plane (c); (397/14), mlofdc (I oscillates with three prism 
faces between I and m, which may be X T; M) ; (397/15), I \ q; mfc dou\ 
(397/16), mlfcftdou Op o>. 

A marked want of symmetry on either side of (a) and (b) charac- 
terises nearly all the crystals. They are all translucent and of a very 
pale bluish-green colour. 

In the General Collection in the same Museum there are other 
Scottish crystals of Topaz, which shew the following combinations : Iff n

Andalusite (398). 

With reference to this mineral from Clashnarae, Aberdeenshire, Mr 
James Currie supplies the following note : " The crystals rarely, as 
noticed by Somerby, form a sheath to a central core of Labradorite ; 
frequently they pass insensibly into the associated Fibrolite. The 
colour is a uniform dull purplish red ; but the author observed that, when 
sectioned, they are seen to have a core which is deep purple, and purple 
spots at the four corners of the transverse section." See also Dr Heddle's 
Chapter viii., Trans. Roy. Soc. Edin., xxxix. 343-4 (1898). 

Fibrolite (399). 

Eegarding this mineral from Clashnarae, Mr Currie also writes : 
" Sometimes it occurs at this locality with a different habit, forming a 
sheath which envelops Labradorite, Quartz, and Andalusite alike. At 
other times it radiates in bundles or fibres through the Labradorite." See 
also op. cit., p. 348-9. 

Kyanite (400). 

The following note by Mr Currie has been abstracted from Mr 
Geo. Barrow's paper, on the thermometamorphism of the rocks of the 
Scottish Highlands. Q.J.G.S. 

" At various points in the belt of metamorphic rock, stretching from 
two miles east of Millden to Millton of Clova and Loch Brandy, the 
Kyanite occurs either more or less aggregated, or in single crystals 
scattered through the mass of the gneiss. In many cases these are 
completely coated with minute crystals of Ilmenite, giving the Kyanite 
a " black-leaded " appearance. The crystal faces are much rounded, and 
as a rule only m and t can be distinguished. The finest crystals occur 
in Glen Effock, bright blue in Quartz : other localities are Atton and 
Bonhard in Glen Clova; head of Water of Saughs; Loch Brandy; 
Loch Lee ; and Bulg." See also Dr Heddle's Chapter viii., Trans. l\oy. 
Soc. Edin., xxxix. 349-353. 

Datolite (401). 

The Scottish Mineral Collection includes a large number of well- 
crystallised specimens of Datolite, from various localities. None of these 
appear to have been referred to in the body of the work nor to have been 
figured. 

Most of the crystals are of small size ; they are implanted, as a rule, 
on c, 001, and their greatest elongation is parallel to 5, 010. The most

usual type consists of a combination of a m m *g c e . (&) is absent. Their 
geognostic relations are with the Zeolites, as they all occur as minerals 
of aqueous origin, and of later origin than that of the enclosing rock. 
They occur in cavities or the sides of fissures. The enclosing rock is 
invariably one of eruptive origin, and its composition ranges from ultra 
basic, as it is at Barn ton, through basic, as at Corstorphine, to subbasic, 
as occurs at Glen Farg. The symbols employed are the same as those 
used by Dana (6th edit.).

Gadolinite (404). 

Two specimens of a diorite-granite from Criffel, which contain much 
Sphene, include also some specimens of a mineral which presents a 
superficial resemblance to Allanite. They were doubtfully referred by 
Dr Heddle to Gadolinite, and, as such, are left in the Scottish Mineral 
Collection. 

Zoisite (406). 

Amongst the specimens of this mineral, from the metamorphic 
marble of Dalnabo, Glengairn, in the Scottish Collection, are several 
minute crystals which show distinct terminations. Some of these have 
been drawn. They each appear to be built up of a number of acicular 
crystals, elongated parallel to the c axis, which forms the base by which 
they are attached, and they consist of various combinations of a, 100 
(oscillating with k, 310, q, 210, and n t 530) ; m, 100 (usually bright and 
smooth, but in some cases striated through oscillations with r, 120 
t, 130, and l y 140), 6, 010 ; d, 101, o, 111 (strongly fluted through oscilla- 
tions with v, 121, and^?, 131) a trace of /, Oil upon one crystal; and 



SUPPLEMENT. 207 

two as yet undetermined and undescribed faces lying between a and d. 
The multiple twinning, the strongly-marked oscillations of adjacent forms, 
and the tendency to unsymmetrical development, are marked charac- 
teristics of the specimens in the Scottish Collection. No trace of the 
I cleavage can be made out on any of the specimens. Specimen 406/23A 
shews maobnpu ; 406/10, a (oscillating with m, Jc, q, n), m (oscillating 
with /), p (oscillating with o, v), p predominating ; 406/10 a , multiple 
twins, a n m d o. None of these appear to have been previously either 
figured or described. 

Zoisite appears to be a not uncommon product of the excessive thermo- 
metamorphism of calcareous strata, and to be confined, at least in 
Scotland, to rocks with that history. As an additional example, may be 
mentioned the occurrence of a gneiss contiguous to limestone on the 
hill nearly two-thirds of a mile slightly south of east of Lochan Cul a' 
Mhoil (Ross-shire 6-inch, map 123), which is stated by Mr Teall to be 
formed essentially of layers of Zoisite and Microcline, mixed with other 
darker layers of Pyroxene, Calcite, and Sphene. [Q.J.G.S., Iv. p. 375.] 
See also Dr Heddle's Chapter viii., Trans. Roy. Soc. Udin., xxxix. pp. 
356-7. 

Epidote (407). 

The Scottish Mineral Collection in the Edinburgh Museum of Science 
and Art includes an extensive series of this mineral, including several 
well-crystallised groups, none of which appear to have been previously 
figured or described.

MEALL AN DAMH, Ben More, Mull. Slender fascicles of minute

208 SUPPLEMENT. 

The majority of Epidotes appear to have been reconstructed from 
what were originally decomposition products of ferro-magnesian silicates, 
which were associated with carbonate of lime, and have afterwards been 
subjected to thermo-metamorphism. 

Allanite (409). 

The specimens of this mineral in the Scottish Mineral Collection are 
nearly all idiomorphic along the zone (cd), forming prisms of the 
combination a c r. In many cases the Allanites form nuclei around which 
crystalline felspar is disposed in radial groups. 

In one single specimen of this mineral (409/27), from the Boat of 
Garten, a distinct termination is seen. It consists of the combination 
nacrd. It has lately been figured by the Editor. 

Unlike Epidote, which is very generally a product of later date, the 
enclosing rock, Allanite appears to be always an original constituent, 
and one of the earlier minerals to consolidate. It seems to be chiefly 
confined to deep-seated rocks of eruptive origin. The other allied and 
essentially isomorphous mineral Zoisite, appears in Scotland to be usually 
a secondary product, due to the thermo-metamorphism of rocks 
contiguous to limestones. 

The presence of Allanite in a rock is often revealed by a rusty stain 
which surrounds the mineral. 

Uigite (411). 

Heddle, Edin. New Phil. Journal, iv. ; Min. Mag., v. 26. " In 
radiating sheafy clusters of plates, in nests in the amygdaloid of Uig, 
Skye, along with Analcime and Faroelite. H. 5'5 ; G. 2-284; lustre 
pearly; colour white, slightly yellowish. 

Comp. according to Heddle :Si0 2 , 45*98, A1 2 3 21-93, CaO 16-15, 
Na 2 4-69, H 2 11 '2 5. B.B. fuses readily and quietly to an opaque 
enamel, which is not frothy. 

Dana remarks that it is near Prehnite in structure. 

Chondrodite (415). 

Greg, Brit. Min., p. 223, states that this mineral " occurs in small 
crystalline masses of a brownish yellow colour in granular carbonate 
of lime, with magnetite and arsenical pyrites, near Loch Ness in 
Scotland." The author (of the present work) has in vain searched for 
it, and believes that the only specimen in existence that in the British 
Museum, South Kensington is merely yellow serpentine. Possibly 



SUPPLEMENT. 209 

the origin of the statement is the occurrence at Millton in Glen 
Urquhart of the mineral to which the author (Dr Heddle) has given 
the name of Xantholite (see Min. Mag. 111. 59) (James Currie). 

Part of the minerals from G-lenelg, at one time doubtfully referred 
to Chondrodite, is now recognised as Forsterite (see Teall, Q.J.Gr.S., 
lv.). 

For the supposed Chondrodite of Eum see " Olivine." 

Calamine (423). 

ARGYLLSHIRE. Strontian. Botryoidal (A. Thorns). 

Staurolite (428). 

INVERNESS-SHIRE. Kirnish Burn, south of Fort William (A. Thorns). 

Stilbite (443). 

Sheaves of crystals of a bright venetian-red or almost vermilion- 
coloured Stilbite occur in veins and coating the joint faces of basalt 
lavas (and even, in some cases, of the adjoining tuffs) in the Lower Car- 
boniferous rocks of Pettycur and Kinghorn on the coast of Fife. The 
crystals resolve themselves into the usual cruciform penetration twins. 

Sphaerostilbite (443). 

(Note by Mr Currie.) The Sphcerostilbite of Beudant, described 
originally from the Faroes, is mere Stilbite in minute crystals, dropped 
upon delicate radiating tufts of Mesolite, the presence of which deter- 
mines the spherical form and causes the gelatin ization with acids. It 
occurs in Skye ; at Storr in minute spheres sprinkled over Faroelite, and 
at Quiraing in spheres the size of a pea with other Zeolites.

Ohlorastrolite (456). 

(Note by Mr Currie.) " A spherulitic mineral occurs upon the north 
slope of Allival in Rum. It consists of small spheres of a pale olive 
green colour with a dark nucleus. They have a finely radiated structure, 
and, at the same time, they are concentrically banded. The mineral is 
not unlike the impure variety of Thomsonite which has been named 
Chlorastrolite." 

Fuchsite (458). 

Micas containing various small percentages of Chromium are of not 
uncommon occurrence in the Highland Metamorphic Series, especially in 
the altered quartzites, according to Mr Geo. Barrow. Mr Barrow

remarks, however, that much of the green micaceous mineral which is 
commonly referred (on account of its colour) to this species is really one 
of the Chlorites. 

Lepidolite (460). 

Is said to have been obtained from " Argyll, in primitive limestone at a 
quarry on the east side of Loch Leven, opposite the inn at Ballichulish. 
Eeported to occur at Dalmally." Greg & Lettsom, Brit. Min., p. 225. 

For Fuchsite, Damourite, Margarodite, and Sericite (see Muscovite 
458). 

Phlogopite (462a). 

There still appears to be some doubt whether some of the light mica, 
occurring in the marbles of the Highland Metamorphic Series, is really 
Phlogopite, as it was at one time assumed to be. Dr Heddle states with 
regard to the light mica of the Gleuelg marble that it is so like a 
Vosges mica named Phlogopite by Prof. King that it is possible it may 
prove to be this most highly magnesian species. (See Trans. Roy. Soc. 
Edin.) 

Ottrelite (467). 

In the Ann. Eep. Geol. Survey for 1895, p. 23, Mr Geo. Barrow 
records the occurrence of this mineral as a product of the thermo-meta- 
morphism of the ancient sediments of the southern border of the Scottish 
Highlands. It is associated with Cordierite, Andalusite, etc.

Wolfram (812). 

MacCulloch states in the Trans. G-eol. Soc. Lond., ii. (1814), that this 
mineral, which had hitherto not been recorded from Scotland, had been 
found in the granite veins traversing the gneiss of Eona. But in the 
Western Isles, published in 1819, he appears to have come to the con- 
clusion that the mineral in question was Magnetite a view which 
Dr Heddle endorsed. Easpe also appears to have made the same 
mistake with reference to Tiree (see Trans. Roy. Soc. Edin., xxx. 
pp. 452-3).

some slight admixture of Feldspar. The replacement in the protoxides

This is very like Hullite in which much of the iron is in the ferrous 
condition. This substance is noticed in the hope of more of it being 
found ; the quantity obtained of it was very small. 

ABERDEENSHIEE. In a deep part of the Quarry of Eubislaw near 
Aberdeen. Imbedded along with crystals of Muscovite in an exfiltration 
vein. It occurred in a solid lump, and also forming a " corded structure " 
pervading Feldspar, identical in appearance with that noted by me in 
Feldspar : it thus occupied the position of the Oligoclase or Albite which 
usually forms that structure. (Abstracted by Alex. Thorns.)

APPENDIX BY THE AUTHOR, 



MINERALS which have been stated to occur in Scotland, but which 
occurrences are either improbable or not sufficiently authenticated : 

MERCURY. Said to have been found in clay near Berwick ; and to 
the amount of several pounds in a peat bog near Loch Fyne. 

PLATINUM. Said to have been found on a farm near Buittle, near 
the mouth of the river Urr, in Kirkcudbright. Possibly Molybdenite. 

CHRYSOBERYL. 

BROOKITE. Some minute crystals upon Ilmenite and also upon 
Eutile from Creag na Caillich seem to be Brookite, but are too minute for 
determination. 

XANTHOSIDERITE. An ochre-coloured iron ore in fibres of two inches 
in length, and containing nearly 20 per cent, of water, is found, rarely, in 
loose pieces along the summit of Hoy Head (St John's Head, Hoy, 
Orkney), and may be this mineral. (Possibly also at Achavarasdale in 
Caithness.)

SYNONYMIC INDEX TO SCOTTISH MINERAL 
LOCALITIES. 

BY J. G. GOODCHILD. 



THE orthography adopted is that used on the maps of the Ordnance Survey : 
other spellings which have been used being given in quotation marks. 
Localities as yet unidentified are distinguished by a prefixed f. 

Following the name of the locality is given the parish or some other 
easily-identified district in which the place occurs, then the name of the 
county, and finally a reference to the Ordnance One-Inch Map (distinguished 
as O.S.) in which the place is found. 

The numbers following (Sp.) refer to the species of minerals known to 
occur at the places mentioned, and are those under which these minerals 
are arranged in the body of the book. They are also the same as are used by 
Dana (Sixth Edition), and in the Collection of Scottish Minerals in the Edin- 
burgh Museum of Science and Art. 

Mr James Currie's information, given while the body of the work was 
passing through the press, has been freely used in this list, and I have to thank 
Mr J. G. Duncan for assisting me in drawing up the lists of minerals from 
those in the Scottish Collection, and both Mr Currie and my colleague Mr 
Macconochie for valuable help in the revision of the proofs of this list.
